The given expression written in surd form is 15√15

From the question, we are to write the given expression in surd form

The given expression is

[tex]15^{3/2}[/tex]

To write the expression is surd form, we will apply one of the laws of indices.

From one of the laws of indices, we have that

[tex]x^{y/n} = \sqrt[n]{x^{y} }[/tex]

Then,

We can write [tex]15^{3/2}[/tex] as

[tex]15^{3/2} = \sqrt[2]{15^{3} }[/tex]

[tex]= \sqrt[]{15^{3} }[/tex]

Simplifying

[tex]\sqrt{3375}[/tex]

Further simplification

[tex]\sqrt{225 \times 15}[/tex]

= [tex]\sqrt{225} \times \sqrt{15}[/tex]

= [tex]15 \times \sqrt{15}[/tex]

= [tex]15 \sqrt{15}[/tex]

Hence, the given expression written in surd form is 15√15

Answer:  (1) Deena and Eduardo, (2) (A) or cube root of 343

Step-by-step explanation:

Number 1 : Deena and Eduardo are correct,

16 x 16 = 256

4 x 4 x 4 = 64

Number 2 : (a) the cube  root. of 343 will give Patel the correct answer,

h^3 = 343

cube root of both sides

so, h. = cube root of 343

Just use a calculator.

First substitute in the numbers and make sure to use ( ) when plugging in negative values. For example, the first one says n=4, you can substitute n from the expression to 4. So n^2 + 3n + 8 will turn into 4^2 + 3(4) + 8 which is 16 + 12 + 8 = 36. You can do this with the other questions.

Step-by-step explanation:

so, pre-image is then doing the opposite :

going up 2 units and left 4 units.

up/down changes y, left/right changes x.

up = positive y direction

down = negative y direction

right = positive x direction

left = negative x direction

just as indicated by the coordinate axes.

so,

going up 2 units = adding 2 to y

going left 4 units = subtracting 4 from x

giving us as pre-image point A

(4 - 4, -5 + 2) = (0, -3)

Answer:

9.8E^-5 (or 9.8*10^-5)

Step-by-step explanation:

0.000098 converted to scientific notation is either 9.8E^-5 or 9.8*10^-5 as they are the same, just different ways of writing it. To get this, you just count the spaces away from the decimal point the number is.

ex.) 0.98 = 9.8E^-1 as it just has to move 1 decimal

980 = 9.8E^1 as it has to move 1 decimal to the positive side

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The number of oranges a grocery store sells at $ 3.12 = 8 oranges

The number of oranges a grocery store sells at $ 1.00 =
The number of oranges a grocery store sells at $ 3.12 / 3.12

The number of oranges a grocery store sells at $ 1.00 = 8 / 3.12

Now ,

The number of oranges a grocery store sells at $ 2.34 = The number of oranges bought by Boubacar

The number of oranges a grocery store sells at $ 2.34 = ( 8 / 3.12 ) x 2.34

So ,

The number of oranges bought by Boubacar = ( 8 / 3.12 ) x 2.34

                                                                           = 8 x 0.75

                                                                           = 6 oranges

Hence , the number of oranges Boubacar buys is 6 oranges

Answer:

b^2 - 4ac ==> what's inside the square root

The answer is the 2nd option

Step-by-step explanation:

b^2 - 4ac represents the number of roots in the quadratic equation. If

b^2 - 4ac>0, then there are 2 roots in the quadratic equation. If

b^2 - 4ac=0, then there is only 1 root. If b^2 - 4ac<0, then the square root of b^2 - 4ac would be invalid since the square root of a negative number has no real solution. Hence, if b^2 - 4ac<0, then there are no roots.

Answer:

The answer should be option B. b^2-4ac

Step-by-step explanation:

If the equation be y = x² + 4 then the inverse function be [tex]f^{-1} (x)=[/tex] ± [tex]\sqrt{x - 4[/tex].

An inverse function, also known as an anti function, is a function that can be reversed into another function. Simply put, if any function " f " takes x to y, then its inverse will take y to x. The inverse function is denoted by f-1 or F-1 if the function is denoted by ' f ' or ' F '.

Let the equation be y = x² + 4    

then the function be f(x) = x² + 4

y = x² + 4

⇒ x = y² + 4

simplifying the above equation, we get

x - 4 = y²

√y² = √x - 4

The value of y = ± √x - 4

Therefore, the inverse function be [tex]f^{-1} (x) =[/tex] ±√x - 4

The value of the expression [tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex] after rationalizing the denominator is [tex]\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex].

A finite collection of symbols that is well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Rationalizing the denominator is the process of shifting a root, such as a cube root or a square root, from the fraction's denominator to its numerator (numerator).

The numerator is the part of a fraction that comes before the vinculum.

The denominator of a fraction is the phrase that comes before the vinculum.

Consider the expression,

[tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]

Now, let [tex]a=\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex]

[tex]a=\frac{(x^{2}y)(y^{3})}{2\sqrt[3]{5} (x^{2}y)(x^{5})}[/tex]

[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} }[/tex]

To rationalize the denominator we multiply and divide the expression by ( ∛5 )².

[tex]a=\frac{y^{3}}{2\sqrt[3]{5} {~}x^{5} } \times \frac{(\sqrt[3]{5})^{2}}{(\sqrt[3]{5})^{2}}[/tex]

[tex]a=\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex]

The value of the expression when rationalized [tex]\frac{x^{2}y^{4}}{2\sqrt[3]{5} x^{7}y}[/tex] is [tex]\frac{5^{\frac{2}{3}}y^{3}}{10x^{5}}[/tex].

Answer: 17.3

Step-by-step explanation:

The factoring of the expression x²=-x+6 is (x-2)(x+3)

By ordering the values, we get:

x² + x - 6 = 0

To solve this exercise, we have to follow the rules of factoring:

1. Looking for the a and b number that state the following equations:

Analyzing that (a*b) is a negative number, it means that (a) and (b) have different signs, and due to the results of (a+b) is positive the higher number has to be the positive one.  

The number could be:

a = -2

b = 3

Confirming:

a + b = -2 + 3 = 1

a * b = (-2) * 3 = - 6

2. Rewriting the factored expression (x+a)(x+b) with the obtained values, we get:

(x-2)(x+3)

Is a technique that consist of decomposition of a factor into a product of another factor, which when multiplied together give the original number.
