That can be true when "x" and "y" are both zero, or both 1.
The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.
sqrt(36) * y2 = 6*y2
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.

No integer squared is equal to 849, but the square root of 849 is 29.138 (5sf)
Approx 5.1962
a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
It is equal to: 2 times the square root of 30
The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.
(x squared plus the square root of 2) times (x squared minus the square root of 2).
24, because the square root of eight times the square root of eight, is eight. the square root of any number, squared, is the original number. then 8 times 3 is 24
