We want to simplify the expression
First we will simplify the exponent:
So now we have
Next, we need to apply the negative exponent property, which states that for any positive value of m and n,
(We flip the fraction to the its reciprocal, then change the sign of the exponent.)
Our new expression is:
Finally, we need to apply the rational exponent rule. Which states for any positive integer value of m and n,
Notice the n becomes the index of the radical, and the m becomes the power of the number under the radical.
So, we have
Our final answer is
