Quotient refers to division:

(8/v)² ⇒ (8/v)(8/v) = 8*8 / v*v = 64/v²

When you raise a fraction to a power, you multiply the fraction by itself according to the power raised.

Then, do the usual steps of multiplying fractions.
1) multiply numerators.
2) multiply denominators
3) simplify fraction produced.

To babysit one child, Fernando charges $10 to drive to the appointment plus $4 per hour. He saves 30% of the total amount he ear
Kazeer [188]
Answer: 10 hours

Explanation:

1) Fernando's earnings:

10 + 4h ← 10 is a fix charge, h is the number of hours and 4 is the rate per hour

2) Fernando's savings

0.30 (10 + 4h) ← 30% = 30 / 100 = 0.3

3 + 1.2h ← distributive property

3) Brenna's earnings

6h ← h is the number of hours, 6 is the rate per hour

4) Brenna's savings

0.25(6h) ← 25% = 25/100 = 0.25

1.5h ←0.25 × 6 = 1.5

5) Equal savings

3 + 1.2h = 1.5h

1.5th- 1.2h = 3 ← transpose terms

0.3h = 3 ← combine like terms

h = 3 / 0.3 = 10 ← divide by 0.3

Answer: h = 10

Multiplying these together, we get:

4 \sqrt{x^2}

The square root of x^2 is x, so we have a final expression of 4x.

What is the difference of the polynomials?(–2x3y2 + 4x2y3 – 3xy4) – (6x4y – 5x2y3 – y5)A–6x4y – 2x3y2 + 9x2y3 – 3xy4 + y5B–6x4y 
saul85 [17]

We have to calculate the difference of the given polynomials, we follows as:

(-2x^{3}y^{2}+4x^{2}y^{3}-3xy^{4})-(6x^{4}y-5x^{2}y^{3}-y^{5})

After opening the brackets, the signs of all the terms changes as there is negative sign before the bracket.

=(-2x^{3}y^{2}+4x^{2}y^{3}-3xy^{4})-6x^{4}y+5x^{2}y^{3}+y^{5})

Combining all the like terms, we get as

=(-2x^{3}y^{2})+(4x^{2}y^{3}+5x^{2}y^{3})-3xy^{4}-6x^{4}y+y^{5}

=-2x^{3}y^{2}+9x^{2}y^{3}-3xy^{4}-6x^{4}y+y^{5}

Option A is the correct answer.
