How do I answer this question

The answer is C. 2.
This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to [tex] 4^\frac{3}{2} [/tex].
[tex] \frac{4^\frac{3}{2}}{4^\frac{1}{2}}=4. [/tex], using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.
Now, we reduced the fraction, so all that is left is [tex] (4)^\frac{1}{2} [/tex]. This is equal to 2.
So your answer is 2.
I hope this helps :)
[tex](\frac{(4^{\frac{5}{4}})(4^{\frac{1}{4}})}{4^{\frac{1}{2}})^{\frac{1}{2}}[/tex]
[tex](\frac{(4^{\frac{6}{4}}}}{4^{\frac{1}{2}}})^{\frac{1}{2}}[/tex]
[tex]({4^{\frac{4}{4}})^{\frac{1}{2}}[/tex]
[tex]({4^{1})^{\frac{1}{2}}[/tex]
[tex]4^{\frac{1}{2}}[/tex]
[tex]2[/tex]
