Question

Rewrite the following without an exponent

Answer 1

The fraction 8/5 is raised to the power -1. If a fraction is raised to a negative power, its reciprocal will be having the positive power.

For example in case of $(x)^{-1}$, it can be written as $\frac{1}{x}$. i.e. to remove the exponent -1 we simply take the reciprocal.

So for given expression the reciprocal will be 5/8

Therefore,

$( \frac{8}{5} )^{-1}= \frac{5}{8}$
