Question

Can somebody explain how to find an estimation of a square root, this book is so confusing...

Answer 1

example, square root of 89

well, where's the closest two perfect squares? 81 is one of them, 100 is the other one. They are 9^2 and 10^2, respectively.

Which one is 89 closer too? It's closer to 81 obviously. 89 isn't half way between 81 and 100, so you know that square root of 89 is less than 9.5. From there you take an educated guess.
