Question

What is the Square root of 45? (Step by step working plz)

Answer 1

• if you simplify it you would have to find factors of 45 that are perfect squares, for example, the square root of 9 times the square root of 5 is the square root of 45 so if you want to simplify it you would need to take the square root of 9 which is 3

so if you put in simplest form you would get 3 root 5

$3\sqrt{5}$
