A square root is the result of "unsquaring" a number, or the reversal of the process of squaring. The root is, as its name implies, a squared number reduced to its most basic form.
Know MoreA square is just a number multiplied by itself. For example, "4 squared" is equal to 4 x 4, or 16. Square roots are the same function, only inverted: the square root of 16 is 4. In this sense, square roots are analogous to subtraction and division. Root numbers represented by whole numbers are considered to be perfect squares. Nonperfect square roots can only be rendered in irrational numbers, or numbers with an ongoing decimal remainder. Nonperfect squares are usually written as approximations.
Learn more about AlgebraThe square root of 256 is 16. A square root is the inverse, or opposite, operation of squaring. This means that the means of finding the square root is to determine which number multiplied by itself results in the integer in question.
Full Answer >The square root of 156 is 12.4899959968. When a person multiplies the number 12.4899959968 by itself, the answer results in 156.
Full Answer >The square root of 8 simplified is 2 times the square root of 2, which equals approximately 2.83. The square root of 8 is found by breaking down 8 into its factors of 4 and 2. The square root of each factor is taken, resulting in 2 and the square root of 2.
Full Answer >The square root of 4 is +2 or -2. The square root of a number can be either positive or negative. This is because the square of +2 is 4 and the square of -2 is also 4.
