Which of the following pairs of numbers provides the best estimate of √59?

√36 and √49

√25 and √49

√25 and √36

√49 and √64

To estimate √59, we want to find two perfect squares that are closest to 59.

√36 = 6 and √49 = 7
√25 = 5 and √49 = 7
√25 = 5 and √36 = 6
√49 = 7 and √64 = 8

Out of these pairs, √49 and √64 provide the best estimate of √59.
