Square RootsTaking the square root of a number is the inverse operation to squaring a number (or multiplying a number by itself).
For example if , then . The symbol tells you to
9 3 find the number that multiplies by itself to give you the inside number.

Parts of a RadicalAn expression that contains a square root is called a radical. It can have three parts.
ba cRadicand: the value you are taking the โrootโ of
Coefficient: it is being multiplied by the radical.
Index: tells you which root you are looking for; if there is not index, it is assumed to be 2.

When dealing with exponents, divide the exponent of the radicand by the index to get the exponent of the root.

Non-Perfect RadicalsSimplify:
Since 24 is not a perfect square, its square root is not a whole number.
To simplify this radical, 24 needs to be rewritten as the product of two factors.
However, one of the factors must be a perfect square.
