Learn how square root means what number multiplied by itself will result in the given number. Created by Sal Khan and Monterey Institute for Technology and Education.

When you have the square root of a fraction, you take the square roots of the numerator and denominator separately. For example, the square root of 16 = 4, while the square root of 25 = 5.

Learn about the square root symbol (the principal root) and what it means to find a square root. Also learn how to solve simple square root equations.

Learn how to find the square root of a decimal number. The problem solved in this video is p^2 = 0.81.

Type in "sqrt", this converts it into "√" radical symbol which you can make square roots from.

In this unit, we review exponent rules and learn about higher-order roots like the cube root (or 3rd root). We'll learn how to calculate these roots and simplify algebraic expressions with radicals.

What are some common ways to simplify square roots? One common way to simplify square roots is to factor the radicand (the number inside the square root symbol) into perfect squares.

Your first step is to think what perfect square divides into 72. People usually look for the greatest one, but it really doesn't matter because you can keep taking factors out.

We're asked to solve the equation, 3 plus the principal square root of 5x plus 6 is equal to 12. And so the general strategy to solve this type of equation is to isolate the radical sign on one side of the …

Of course, simplifying the result assumes you understand: a) order of operations; b) how to simplify a square root; c) how to reduce fractions. If this doesn't make sense, then please ask a more specific …
