Question

Simplify (2) to the power of -3

Answer 1

We are to simplify

`2^(-3)`

From the the laws of indices,

`\begin{gathered} x^(-m)\text{ =}(1)/(x^m) \\ \end{gathered}`

Aplying this law to the question, we have

`\begin{gathered} 2^(-3)=(1)/(2^3) \\ =(1)/(8) \\ \text{ The answrer is }(1)/(8) \end{gathered}`
