Let's check:
8 ^ 2 = 64
9 ^ 2 = 81
Is the square root of 83 between 64 and 81? If not then look at the next set of perfect squares.
If you used the calculator that this site is supposed to be, you would find
the sqaure root of 83 is 9.1104335791442989
I'm pretty sure if you try to square root and the outcome is a decimal, you do it this way
√20
√18 x 2
9 √2
9 x 1
9
This is probably wrong, and I think this way only works with variables.... I'm sorry
