Simplifying Square Roots When not a Perfect Square Numbers that are imperfect squares are those that, when evaluated, do not give solutions that are integers. Simplifying Expressions Containing Square Roots In order to write radical expressions correctly, they have to be written in their simplest form. Evaluating Square Roots of Perfect Squares Squares and square roots are inverse, or opposite, operations involving radicals.

In this problem, radical 80 has radical four as a perfect-square factor, so we simplified it to radical 4 radical Then, radical 20 was further simplified to radical 4 radical 5 to produce another perfect-square factor. Since both radical fours are equal to two, we reduced them and worked out the multiplication. If your answer contains a radical that has a perfect square as a factor, it is not completely simplified.
Simplify the following radicals. In some cases, the radicals may be perfect squares, and in other cases, it may not be possible to simplify them further.
Keep in mind that since some radicals have multiple perfect-square factors, there may be different ways to arrive at the correct solution. If your answer matches the ones below, then it is correct even if you arrived at that answer in a different way. Since radical 26 does not have any factors that are perfect squares, it cannot be simplified. If not, you may have used this method to arrive at the same answer:.

How to Simplify Radicals A radical is the root such as square root or cube root of a number.
Simplifying Perfect Squares If a radical is a perfect square, all you need to do to simplify it is to write it as the corresponding integer. Simplifying Imperfect Squares Radicals have factors just like integers do. Using Factors to Simplify Radicals How does factoring radicals help us to simplify them?
How to Simplify Radicals. A radical is the root (such as square root or cube root) of a number. The radicand is the number under the radical sign. Some radicals are perfect squares because they can be written as integers. For instance, radical nine is equal to three, since 3 x 3 = 9. Other perfect squares include radical 16, radical 25 and radical .
Multimedia explanation for Algebra 1: Simplifying Radicals. Connection Speed.
Question description. In this discussion, you will simplify and compare equivalent expressions written both in radical form and with rational (fractional) exponents. Simplifying Perfect Help If a radical is a perfect radicals, all you need to do to simplify it is to help it radicals the corresponding integer. Simplifying Imperfect Squares Radicals have factors just like integers do.
Radical expressions are simplified when any square roots are solved, so the expression is in its simplest form. For example, √(a 18) can be simplified as 10a 9 because both factors are perfect squares. Before operations can be performed with expressions involving radicals, the radicals must be simplified. No perfect square factors are under the radical sign.
