Exponents are usually written like this: 3^2 means "3 to the second power". Square roots are often written with sqrt in front, such as as sqrt(5)
Replace the radical sign with the exponent 0.5. For example sqrt(7) = 70.5
They are inverse relations. That is,if A and B are any numbers andif A is the square of Bthen B and -B are the square roots of A.
See the related link for a detailed description of a manual method for calculating square roots.
Working the exponents or roots is first in the order of operations.You do those even before multiplication or division.

The square root of every perfect square is an integer. However, there are also square roots of numbers that are not perfect squares.
I posted an answer about cube roots of complex numbers. The same info can be applied to square roots. (see related links)
C = w r2Divide each side by 'w' :C/w = r2Take the square root of each side:sqrt(C/w) = r
See related links for methods for calculating a square root by hand.

Roots in math are like the opposite of exponents, kind of like multiplying and dividing, and adding and subtracting. If you take square a number, and then take the square root of that number, you just undid everything. If 9 squared is 81, then the square root of 81 is 9. If 5 cubed is 125, then the cubed root of 125 is 5.
