The number is 4
(4+3) * (4+3) = 49
(4+2) * (4+2) = 36
49 - 36 = 13
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
The sum of a number plus 3 to the square root of 9 to the sum of 2 would equal -2. This is a math problem.
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.
