Whenever you have a number times itself x times, you put the number being repeated on the bottom as the base, and the number of times it is repeated is put on the top right corner as the exponent.

#### Explanation:

Here's an example -- 2^4. 2 is the number being multiplied, so we compute that number as the base. The number of times 2 is being repeated is four. Thus the result 2*2*2*2, in other words, 2^4.

Back to the question. Number being repeated? y. Number of times y is being repeated? 2. Thus the answer is y^2.
