find the numerical equivalent of 2^5 * 2^-2

Question

1. 128
2. 8
3. 2
4. 16

Answer 1

To find the numerical equivalent of 2^5 * 2^-2, we can simplify the expression first.

Recall that when multiplying numbers with the same base, you add their exponents. Therefore, we have:

2^5 * 2^-2 = 2^(5 + (-2)) = 2^3

2^3 means 2 raised to the power of 3, which is equal to 2 * 2 * 2.

Hence, the numerical equivalent is 8.

Therefore, the correct answer is option 2.
