Which shows the correct simplification of product of powers? 1.) 78 · 7-4 = 78· (–4) = 7–32 2.)78 · 7–4 = 78 ÷ (–4) = 7–2 3.)78 · 7–4 = 78 + (–4) = 74 4.)78 · 7–4 = 78 - (–4) = 712

The answer choice which shows the correct simplification of product of powers is:

This refers to the mathematical property which states that when there is a multiplication of two powers that have the same base, then there would be the addition of exponents.

From the given choices, we can see that the powers are not given, so we can solve using inference.

This posits that  (7^8) * (7^-4) was the product that was intended to be simplified and this law shows:

Hence, if we add the powers, then the correct answer would be option C because they are of the same base.

step-by-step explanation:

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
