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:

Step-by-step explanation:

The bank can borrow $6440 based on the $7000 deposit.

The following deposit amount: $7000

Because the reserve rate is 8%, the bank will reserve 8% of the 7000. The remaining funds can be lent by the bank.

7000 × (8/100) = amount set aside

= $560

Thus, the reserve deposit is $560.

Amount the bank is willing to lend = 7000 - 560 = $6440

Thus, the bank can lend $6440 based on a deposit of $7000.

The equation which can be used to find x is, [tex]\bold{\frac{1}{x} =\frac{1}{14} +\frac{1}{10} }[/tex]

The time taken by Franklin to make a 200 sq. foot cement patio = 14 hours

The time taken by Scott to make a 200 sq. foot cement patio = 10 hours.

Let x be the number of hours it would take Franklin and Scott to make the patio together.

Then x = 14 x 10 / (14 + 10)

⇒ 1 / x = (14+10)/(14 x 10)

⇒ 1/x = 1/14 +1/10

This is the equation to find the number of hours taken by Franklin and Scott together.

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.

5(3x+2)+7=6+2(3x−8)

1: Simplify both sides of the equation.

5(3x+2)+7=6+2(3x−8)

(5)(3x)+(5)(2)+7=6+(2)(3x)+(2)(−8)(Distribute)

15x+10+7=6+6x+−16

(15x)+(10+7)=(6x)+(6+−16)(Combine Like Terms)

15x+17=6x+−10

15x+17=6x−10

2: Subtract 6x from both sides.

15x+17−6x=6x−10−6x

9x+17=−10

3: Subtract 17 from both sides.

9x+17−17=−10−17

9x=−27

Based on the change in the temperature of the city over the 4-week period, the expression to show the average change in temperature each week is -20 / 4

When the expression is simplified, the result if -5°C which means that the temperature reduced by 5°C every week.

The average temperature change of the city each week can be found by:

= Total change in temperature / Number of weeks

Solving gives:

= -20 / 4

= -5°C

This means each week for the 4-week period, the temperature of the city decreased by 5°C.

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

The midpoint of AR is (1/2 , 1).

Let the points be:

A(0,0) = (x₁,y₁)

B(1,2) = (x₂,y₂)

Midpoint = (x₁₊x₂/2) , (y₁₊y₂/2)

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places.

= (0₊1/2) , (0₊2/2)

=(1/2 , 2/2)

= (1/2 , 1)

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 numerical expression using commutative property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.

Multiplication is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.

Now the given exponent is,

2⁸

Now, 8 can be written as using associative property of addition,

8 = 2 + 2 + 2 + 2

Thus we can write,

2⁸ = 2^( 2 + 2 + 2 + 2 )

Using exponential property

x^(a + b) = x^a . x^b

Thus we get,

2⁸ = 2^2 . 2^2 . 2^2 . 2^2

Thus numerical expression for 2^8 = 2^2 . 2^2 . 2^2 . 2^2

Solving we get,

2^8 = 4 x 4 x 4 x 4 = 256

Thus, the numerical expression using exponential property of multiplication that is equivalent to 2⁸ is 2² x 2² x 2² x 2² = 256.
