The simplified form of the given equation is 
We have given that,

Apparently, you want to simplify the given equation,

The applicable rules of exponents are,
<h3>What is the exponent rule?</h3>
(a^b)(a^c) = a^(b+c)
1/a^b = a^(-b)
(a^b)^c = a^(bc)
So the expression simplifies as

Therefore the simplified form of the given equation is
