Square roots, designated by the √ symbol, are operations that find a number which, when multiplied by itself, create the number under the radical symbol. Simplifying the square root of a number, or radicand, requires fac... More »

In order to simplify square roots with variables that are to be multiplied, treat the variables as factors. Once the radicands are factored completely, cancel any like terms and multiply the simplified square roots. 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 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 »

In mathematics, a variable is a symbol used for a number not yet known, while a constant is a number or symbol that has a fixed value. The value of a variable can change depending on the equation, while the value of a co... More »

Expressions are simplified by using the acronym PEMDAS, which stands for parentheses, exponents, multiplication, division, addition and subtraction. This acronym is helpful because it tells the order to perform the mathe... More »
