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.

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.

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's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.

X + y

X= plus or minus 1

It's the longest side. If a and b are the shorter sides, the square root of a squared plus b squared will equal the length of the hypotenuse

(x squared plus the square root of 2) times (x squared minus the square root of 2).

square root of (x2 + 1) = no simplification (square root of x2) + 1 = x + 1

2 squared equals 4 - wherever it is found!

The diameter of a rectangular area is the square root of the length squared plus the width squared. D = √(L²+W²).

The surface area is length times width plus length. Then you find the square root of the width divided by two and then squared. You add this to the height squared plus the width. The width is multiplied by the square root of 1/2 squared plus the height squared.

That can be true when "x" and "y" are both zero, or both 1.

-3 squared = 9. The square root of -9 is 3i, i being the square root of -1

The square root of A2 is... A !

The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8

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.

The square root of 324 is 18. Do you mean the square root? Or do you mean the root of 324, squared? If you do, and by "root" you mean "square root", then 324.

It is equal to the square root of 147 or about 12.124 to 3 decimal places

Because it is mathematically incorrect. a^2 + b^2 = c^2 Take square root of both sides. SQRT (a^2 + b^2) = c So you see, it is not a plus b equal c.
