Expand each logarithm.
log a²b³ / c⁴
The answer to the present question is: log(a²b³/c⁴) = 2log(a) + 3log(b) - 4log(c)
For solving this kind of question, we are going to use these three identities:
log(x*y) = log(x) + log(y) ....(1)
log(x/y) = log(x) - log(y) ....(2)
log(xⁿ) = nlog(x) ....(3)
So, using (2), log(a²b³/c⁴) may be written as: log(a²b³) - log(c⁴) ....(4)
Again, using (1), log(a²b³) are often written as: log(a²) + log(b³) ....(5)
Now, Putting equation (4) in equation (3), we get:
log(a²) + log(b³) - log(c⁴) ....(5)
Now, using (3), expanding all the terms, we get:
log(a²) = 2log(a)log(b³) = 3log(b)log(c⁴) = 4log(c)
Putting of these in equation 5, we get:
2log(a) + 3log(b) - 4log(c)
Therefore, log(a²b³/c⁴) = 2log(a) +3log(b) - 4log(c)

Todd made feathery cat toys to sell at a craft fair. he made 198 cat toys, and each toy used 6 feathers. todd worked out that he used 718 feathers to make the cat toys. does that sound about right?
When Todd says that he used 718 feathers to make the cat toys, it does not sound right.
To solve this problem, we have to state the equations using the information of the problem
Information about the problem:
No. of toys= 198No. feather per toy= 6 feather/ toyTodd's calculated = 718 feathers in totalCalculating how many feathers Todd should use to made 198 cat toys:
Total feathers = No. of toys * No. feather per toy
Total feathers = 198 toys * 6 feather/ toy
Total feathers = 1188 feathers
With the calculate we can confirm that Todd's calculate is not right because:
Total feathers > Todd's calculated
1188 feathers > 718 feathers

We need to know about logarithm to solve this problem. The exponential form of the logarithm is [tex]2^{7} =128[/tex].
Logarithm is the exponent that is raised to a base to get a certain number.There are a few rules of logarithm, log a+ log b can be written as log ab, log a -log b can be written as log a/log b, when the number whose logarithm is being calculated is raised to a power, then the power can be multiplied to the log itself. Logarithm when written as log without base mentioned, the base is 10, the log of a number that is same as the base is always 1, the log of 1 is always 0 because a nonzero number raised to 0 is always 1. To write a logarithm in exponential form we have to raise the value of the logarithm to the base which is equal to the number whose logarithm we found.
[tex]log_{2} 128=7[/tex] can be written as [tex]2^{7} =128[/tex]

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Let the cost of the groceries be represented as "c", then we have;
Cost price + VAT = c + (5% of c)
In order to get the cost, c, that make him spend as close to $15. Since the tax is 5% of the cost price, then the cost price will be close to $15.
Let c = $14.20, then;
So that,
c + (5% of c) = 14.20 + (5% of 14.20)
= 14.20 + 0.71
= $14.91

Find the area of a cement walkway of width x meters around a 50m by 25m pool.
The area of a rectangular cement walkway of width x meters around a 50m by 25m pool is 4x²+150x sq. meters.
What is an area of a rectangle?Rectangle area in geometry refers to the area that a rectangle occupies on a two-dimensional plane. A rectangle is a form of a quadrilateral, a two-dimensional object with four sides and four vertices. The four angles of the rectangle are all perfectly right angles or 90 degrees. The opposing sides of the rectangle are equal and parallel.
Area of Rectangle = Length × Breadth
In the given question,
The width of the walkway is x meters.
Width of the pool= 25+2x meters
and the Length= 50+2x.
So the area of the walkway with the pool is
= (25+2x)+(50+2x)
= 1250+100x+50x+4x²
= 4x²+150x+1250 sq. m
Area of the pool= 50x25
= 1250 sq. m
Area of the walkway= 4x²+150x+1250-1250
= 4x²+150x sq. meters.

Arturo lives in colorado, which has a state income tax rate of 4.63%. he earns $1,345 biweekly. how much state income tax is withheld from each of his paychecks?
If Arturo lives in colorado, which has a state income tax rate of 4.63% and he earns $1,345 biweekly, then the amount of state income tax withheld from each of his paychecks is equal to $62.27.
The state income tax withheld from each of his paychecks can be determined by the percentage formula;
P% × x = y
Here,
P% is the state income tax rate
x is the dollars earned biweekly
y = state income tax withheld from each of his paychecks
As the state income tax rate is equal to 4.63% and the amount earned biweekly is equal to $1345, therefore;
P% × x = y
4.63% × 1345 = y
4.63% can be converted into decimal form as follows,
4.63% = 4.63 / 100 = 0.0463
Therefore,
0.0463 × 1345 = y
y = 62.27

The measure of angle R is 6 less than 5 times its complement. What is the measure of the complement of angle R?
a. 16
b. 74
c. 45
d. 90
Answer:
a
Step-by-step explanation:
the complement of R is 90 - R , then
R = 5(90 - R) - 6
R = 450 - 5R - 6
R = 444 - 5R ( add 5R to both sides )
6R = 444 ( divide both sides by 6 )
R = 74°
complement = 90° - 74° = 16°
Option(a) 16 is correct option, the measure of the complement of R is 16
What is the complement of an angle?Two angles are complementary if their sum is 90°.
Let x be an angle and y be its complement of x then x + y = 90°.
Let the measure of the complement of R be x
Given that the measure of angle R is 6 less than 5 times its complement
Then 5 times the complement of R = 5x
And 6 less than 5 times the complement of R = 5x-6
Thus, R = 5x -6
∴ R + complement of R = 90°
⇒5x-6 + x = 90
⇒6x = 96
⇒x = 96/6 = 16
Therefore, the measure of the complement of angle R is 16 and option (a) is correct option.

ln (2 x-1) = 3.5
Using the exponential property of the log.

2x = 33.11 + 1
2x = 34.11

The addition expression (-3) + (-1) on a number line is : (-4).
Here, we have,
To represent the addition expression (-3) + (-1) on a number line,
we would start at -3 and move to the left by 1 unit.
Here's how we can explain it step by step:
Start at -3 on the number line.
Since we have a negative sign in front of both numbers, we will move to the left (in the negative direction) on the number line.
The first number, -3, indicates that we will start at -3 on the number line.
The second number, -1, indicates that we will move to the left by 1 unit from -3.
When we move to the left from -3 by 1 unit, we will reach -4 on the number line.
So, (-3) + (-1) represented on the number line means starting at -3 and moving to the left by 1 unit, resulting in -4.
