To find a number's square root, determine which two perfect squares the number lies between and estimate a fraction between those two perfect square roots. If it is a perfect square itself the square root can be arrived ... More »

The numerical value of the square root of 11 is approximately 3.317, although the exact number has many more decimal places. Because 11 is a prime number, the square root of 11 cannot be written in a simplified form by f... More »

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. More »

Simplifying square roots involves pulling as many integer factors outside the square root as possible. For example, the square root of 48, or sqrt(48), is equal to sqrt(16) * sqrt(3), which is 4 * sqrt(3). For a measurem... More »

To estimate a square root without a calculator, determine the two perfect squares that come before and after the given number. Then using the square roots of the perfect squares as guides, estimate the given number’s squ... More »

In order to calculate the square root of a non-perfect square number, first find two perfect squares between which the number lies. Second, divide the number by one of the two square roots. Thirdly, take the average of t... More »

An integer is a whole number that is not a fraction. Integers include both positive and negative numbers, and there are several rules for adding integers. More »
