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 »

Find the square root by finding the number that, when multiplied by itself, gives you the root number. For root numbers that are not perfect squares, there is a separate process to finding the square root. More » Math Exponents

To calculate the square root of any number, estimate by using the closest perfect square, and divide the number for which you want the square root by the root of that perfect square. Average the result with that perfect ... More » Math Exponents

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 » Math Algebra

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 »

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 » Math Exponents

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 »
