What is the simplest radical form of a number?

Back

The simplest radical form of a number is when the radical (square root, cube root, etc.) is expressed in its most reduced form, meaning that there are no perfect square factors (or higher powers) under the radical.

How do you combine like terms in expressions involving radicals?

Back

To combine like terms in expressions involving radicals, ensure the radicals are the same (same index and radicand) and then add or subtract the coefficients.
