Question

Simplify write your anser using only Positive exponents

8^-2 x a^7

Answer 1

Recall that a negative exponent indicates the reciprocal of the base raised to the positive exponent. That is,

x^(-n) = 1/x^n

Using this rule, we can write:

8^-2 x a^7 = 1/8^2 x a^7 = a^7/64

Therefore, the simplified expression with positive exponents is a^7/64.
