63

Explanation:

We can start by first realizing that 4 is really just 2. So that makes it 26.

We can take the next step by getting the square root out of the denominator.

(26)(66) = 26(6)2.

The squared and square root cancel each other out, leaving just 266.

Then you can simplify the 2 in the numerator and 6 in the denominator to just get 163, but you would not write the 1, so 63.
