Question

Explain why the product of power property cannot be used to simplify 2^7 *b^7

Answer 1

See below.

Explanation:

Because the product of power property is only valid when the BASES are equal . For example 3^2 * 3^4 = 3(2+4) = 3^6 - the bases are both 3.

In the example in the question the bases ( 2 and b) are not equal.
