sqrt(45) = sqrt(9 x 5) = sqrt(9) x sqrt(5) = 3 x sqrt(5)

In general, to simplify square roots, you just need find two terms whose product are the original number. In this case those two terms are 9 and 5, and the square root of 9 is 3.

The answer is: 3 x sqrt(5)
I cant use the square root symbol lets use the word "root" to represent square root. The answer would be 3root5
