What type of number does the denominator of a radical expression contain after rewriting it without radicals?
Rationalize the denominator
We are asked to complete the following sentence.
You ? of a radical expression by rewriting it without radicals in the denominator. |
yousuggests that we should complete it with a verb. We need to think of a name for the process of rewriting a radical expression without radicals in the denominator. First, let's recall what a radical expression is.
Radical Expression | 27 | 352 | 313 |
---|---|---|---|
Multiply | 27⋅22 | 352⋅55 | 313⋅33 |
Simplify | 272 | 3⋅525 | 3133 |
Final Expression | 272 | 1525 | 339 |
Now each expression has a rational number in the denominator. Therefore, we rationalized the denominators of the radical expressions. Let's complete the given sentence.
