31 paź 2021 · How to: Solve a Radical Equation. Isolate a radical. Put ONE radical on one side of the equal sign and put everything else on the other side. Eliminate the radical. Raise both sides of the equal sign to the power that matches the index on the radical. This means square both sides if it is a square root; cube both sides if it is a cube root; etc.
For instance, √25 = 5 since 5 x 5 = 25. However, radicals are not just square roots. We also have cube roots. The cube root of the number is the number that, when multiplied by itself thrice (or three times), will produce the original number. For instance, ∛27 = 3 since 3 x 3 x 3 = 27.
A radical expression is said to be in standard form if the following conditions hold: 1. The radicand is positive. 2. The radical index is as small as possible. 3. The exponent of each factor of the radicand is a natural number less than the radical index. 4. There are no fractions in the radicand. 5.
