Which rules of exponents will be used to evaluate this expression? check all that apply. product of powers
quotient of powers
power of a power
power of a product
negative exponent
zero exponent

We are given the expression:

Let us evaluate the expression step by step:

Step 1:

Power of a power: In this rule we multiply the powers 4 and (-5) in the numerator.

Step 2:

Quotient of power: Here we will subtract the power of denominator from numerator.

Step 3:

Negative exponent: Here we take reciprocal of what we got in step (2) , that will make the power positive.

We will use three rules as shown above .

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
