Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that
(<span>8.4852...)
</span>is equal to

If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.
So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!
They need 4 more because 12+50+34=96 96-100 is 4 hope this helps ya
