Question

Identify the value for the variable

Answer 1

-12, 4

Explanation:

7^-9 x 7^-3 = 7^-12

When you multiply exponents with the same base, you add them.

11^-4/11^-8 = 11^4

When you subtract exponents with the same base, you subtract the exponent in the numerator by the exponent in the denominator.
