How do we eliminate a cube root
WebWe can raise numbers to powers other than just 2; we can cube things (being raising things to the third power, or "to the power 3 "), raise them to the fourth power (or "to the power 4 "), raise them to the 100 th power, and so forth. In the same way, we can take the cube root of a number, the fourth root, the 100 th root, and so forth. Just as the square root undoes … Web1. Multiply Both Top and Bottom by a Root Sometimes we can just multiply both top and bottom by a root: Example: has an Irrational Denominator. Let's fix it. Multiply top and bottom by the square root of 2, because: √2 × √2 = 2: Now the denominator has a rational number (=2). Done!
