To get the simplest radical root form for a non-perfect square, always factor out the number first. So, for 18, find the factors. 18 6 3 2 3 3 2 3u00b2

so, when you find a pair of the same two numbers, they become squared. Eliminate the squared signs; that number goes to the left, and the left over numbers are multiplied and are put into the square root sign. So, you end up with the final answer:
