02 + 02 = 0; all other numbers squared are greater than 0. Otherwise 25 (= 52) = 32 + 4262 + 82 = 100√100 = 10; √1000 ≈ 31.6, so largest square less than 1000 is 312Between 100 and 1000 there are 31-10 = 21 square numbers (22 if 100 itself is included since 100 = 102)
There are eight such numbers.
There are 31 perfect square numbers between 1 and 1000 (including 1).
sqrt(1000) = 31.62... So there are 31 (or 32 including 0 = 02).
