| The process of writing an equivalent expression, but without a radical in the denominator is called _________? | rationalizing the denominator |
| The process of writing an equivalent expression, but without a radical in the numerator is called __________? | rationalizing the numerator |
| To rationalize the denominator of 9 / √4, we multiply by? | √4/√4. |
| We use power rule to? | Eliminate the radical. |
| Would a appropriate radical undo an exponent? | Yes. Example: Cube root 2^3=2 |
| Can the right power undo a root? | Yes Example: Forth root 3^4=3 |
