<em><u>Solution:</u></em>
We have to simplify the given expression
<em><u>Given expression is:</u></em>

<em><u>Use the law of exponent</u></em>

<em><u>Thus the given expression becomes,</u></em>

<em><u>Simplify the exponents</u></em>

Again use the law of exponent for 

<em><u>Substitute in above expression</u></em>

Thus the given expression is simplified
