Simplifying Radical Expressions with Variables Worksheet - Concept - Problems with step by step explanation. Skip to Content. Step 1 : Decompose the number inside the radical into prime factors. We can simplify radical expressions that contain variables by following the same process as we did for radical expressions that contain only numbers. Simplify the expressions both inside and outside the radical by multiplying. For every pair of a number or variable under the radical, they become one when simplified. Multiply all numbers and variables inside the radical together. In both cases, you arrive at the same product, \( 12\sqrt{2}\). A radical expression is considered simplified when there are no perfect root factors left in the radical. For example, These types of simplifications with variables will be helpful when doing operations with radical expressions. When the radical cannot be conveniently decomposed/factored into two same terms, we factor the radical into a product of a perfect square and a non-perfect square. More Examples: 1. Video transcript. Factor the. Multiply all numbers and variables outside the radical together. Simplify: √252. It does not matter whether you multiply the radicands or Similarly, is simplified because there are no perfect cube factors in 4. We will start with perhaps the simplest of all examples and then gradually move on to more complicated examples . For example, is considered simplified because there are no perfect square factors in 5. A perfect square is the product of any number that is multiplied by itself, such as 81, which is the product of 9 x 9.

If you have square root (√), you have to take one term out of the square root for every two same terms multiplied inside the radical. type (2/ (r3 - 1) + 3/ (r3-2) + 15/ (3-r3)) (1/ (5+r3)). When the radical is a square root, you should try to have terms raised to an even power (2, 4, 6, 8, etc). A perfect square is the product of any number that is multiplied by itself, such as 81, which is the product of 9 x 9.
