How do you know if a radical expression is in simplest form?

You're welcome.

:-)

To determine if a radical expression is in simplest form, follow these steps:

1. Simplify the radicand: The radicand is the expression under the radical symbol (√). Simplify it as much as possible by factoring out any perfect square factors and reducing fractions.

2. Remove perfect square factors: If there are any perfect square factors inside the radical, simplify them by taking their square root. For example, if you have √18, you can simplify it as √(9 x 2). Since 9 is a perfect square, you can take its square root, which is 3. Therefore, √18 simplifies to 3√2.

3. Eliminate duplicate radicals: If you have multiple radicals with the same radicand, combine them into a single radical. For example, if you have √16 + 2√16, both radicals have the radicand 16. Adding them together gives you 3√16.

4. Isolate the square root: If possible, remove any other operations that are present within the radical such as addition, subtraction, multiplication, or division. Simplify these operations separately and then combine them with the radical expression.

By following these steps, you can simplify a radical expression and determine if it is in its simplest form.

I don't know, but Google does.
