Squares and Roots Squares a Num

Squares and Roots of Squares a Numbers - you guys Must have known that the square of a number is the repeating multiplication of the number twice. If X is a number, then the square of X is X 2 . The examples below are some quadratic forms:

a. 3 2 = 3 x 3 = 9
b. (1,2) 2 = 1,2 x 1,2 = 1, 44
c. (-5) 2 = (-5) x (-5) = 25

Then, what exactly is called the square root? The square root of a number is a nonnegative number which, when squared is equal to that number. It can be said that the square root of a number is the inverse of the square of a number. If Y is the square of the number X (Y = X 2 ) then the number X is the square root of the number Y (X = √Y). The examples below are some form of square root:
