Let's examine some perfect squares that are close to 1000Max@Math Revolution wrote:[GMAT math practice question]

A. 29²
B. 30²
C. 31²
D. 32²
E. 33²
30² = 900
31² = 961
32² = 1024
So, 1000 lies between 961 (aka 31²) and 1024 (aka 32²)
1000 is closer to 1024 (aka 32²) than to 961

We see that 32^2 = 1,024 and 31^2 = 961, so 32^2 is closest to 1000.Max@Math Revolution wrote:[GMAT math practice question]
