What is the square root of 18 written in simplest radical form
1 answer:
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 3²
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:
