Question

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

Answer 1

You can try to factor the number out and see if any of the factors are duplicated

Example:
square root of 50:
50 = 5 * 5 * 2 <-- there is two 's so it can be simplified more


square root of 39:
39 = 3 * 13 <-- no duplicate factors

Answer 2
