<u>Given</u>:
The given expression is 
We need to determine the equivalent expression.
<u>Equivalent expression:</u>
Let us determine the equivalent expression.
The equivalent expression can be determined by simplifying the given expression.
Hence, let us apply the exponent rule to simplify the given expression.
Thus, applying the exponent rule,
, we get;

Rewriting the expression, we get;

Simplifying, we get;

Thus, the equivalent expression is 
Hence, Option C is the correct answer.
domain is the numbes you are allowed to use for x
what I usually do is just find the numbers that aren't allowed in the domain. such numbers are numbers that cause a division by 0 or a squaer root of a negative number
given
, there are no numbers that you can use for x that will cause a division by 0 or a square root of a negative number
so domain is all real numbers or D={x | -∞<x<∞}
