Question

The value of (2^-5÷2^-2) is

Answer 1

Answer:

${2}^{ - 5} \div {2}^{ - 2} \\ = \frac{1}{ {2}^{5} } \div \frac{1}{ {2}^{2} } \\ = \frac{1}{ {2}^{5} } \times {2}^{2} \\ = \frac{1}{ {2}^{3} } \\ = \frac{1}{8}$

Answer 2

$2^{-5} ÷ 2^{-2}$

We are to subtract powers (indices) if the bases are the same and they are dividing each other. So we'll say -5 - -2 = -5 + 2 = -3

So the answer to your question is :

2^-3
