We are given expression :
.
We need to simplify it.
<em>First we need to apply quotient rule of exponents.</em>
According to quotient rule of exponents, we need to subtract powers.
Therefore,
.
<em>Now, we need to apply exponents of exponent rule in next step.</em>
According to exponents of exponent rule, we need to distribute whole exponent inside exponent.
Therefore,
.
<h3>Therefore, final answer is

.</h3>
