Answer:
Simplifying the expression
so, there is only one power of each base we get 
Option D is correct answer.
Step-by-step explanation:
We need to simply the expression
so, there is only one power of each base.
Solving:
We can write it as:

Now using exponent rule: 

Now using the exponent rule:
the bases should be same

So, simplifying the expression
so, there is only one power of each base we get 
Option D is correct answer.
