This is the way that I find easiest, and I shall try to explain it best.
so here, I'll give an example say your trying to find the square root of 9
what times what equals 9? 3 X 3 does so your square root of 9 would be 3
say you have to find the square root of 16
4 X 4 so the answer is the square root if 16 is 4
last example, say your trying to find the square root of 25
5 X 5 is 25. so therefore the answer is the square root of 25 is 5
I hope this is helpful
