Question

How do you simplify `sqrt (30)`?

Answer 1

This expression cannot be simplified further.

Explanation:

You look for perfect squares that can go inside this number. The perfect squares are : `1`, `4`, `9`, `16`, `25`, `36`... it continues infinitely but since we have already passed the desired number of `30`, I will stop here.

`1` does not count since you are just dividing by `1`, which is basically the same as doing nothing.

Since `4`, `9`, `16`, `25` are not factors of `30`, or any other perfect square, this expression cannot be simplified further.
