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.

Yes. Assuming you can use any mathematical formula that only uses four fours, you can take the square root of four (2) plus four (6) plus four over four, which simplifies to 1 over one, which is one, you simply get two plus four plus one, or seven
