22

Explanation:

There are 2 solutions :)

The first solution is:

Since ab=ab, where b is not equal to 0.

First we simplify the numerator, since there is no exact value of 32 we take its perfect squares. 16 is a perfect square since 44=16. Dividing 32 by 16, we get 162=32, therefore:

32=162
=42

Since now we're done in the numerator, we're gonna simplify the denominator, since 4 is perfect square, 4=22, the 4 is equal to 2.

Plugging all the answers, we get:

422

since 4 and 2 is a whole number, we can divide these 2 whole numbers, we get:

22

this is the final answer :)

the 2nd solution is:

First we simply evaluate the fraction inside the radical sign (square root)

324=8

since, 324 = 8, then we get 8

8=42

=22
