Well you multiply 2 by a = 2x6 so you would get 12 plus 4 and get 16 than you multin multply b squared so squared is 2 to the second power and b = 2 so 2x2=4 so 16 / 4 = 4 so y=4 and i'm in sixth grade and i did all this on my own and i have the honors classes 1st-homeroom period and 8 wasn't on the answers cause the question was multiple choice and the answers were 4 5 13 and 16 so i don't know how that person got 8 if that person is older than me than i feel very bad for that person but younger, they should still know pre-algebra.

When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?

Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
