Best Answer

I think you mean square root. The square root of a number is that number when multiplied by itself will give the original number. For example the original number is 4, then we know that 2 x 2 is 4, hence 2 is the square root of 4. We also know that -2 x -2 is also 4, hence 4 has two square roots, +2 and -2

Similarly 9 has two square roots, +3, and -3

Similarly 16 has two square roots, +4, and -4

Not all numbers have such whole numbers for their square roots. For example the square roots of 2 are nearly equal to +1.4142 and -1.4142. Similarly the square roots of 3 are nearly equal to +1.73205 and -1.73205

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.
