Probably the best approach is to calculate the square root of 1000 and then put a decimal in the result.blaster wrote:Of the following, which is most nearly equal to sqrt(10)?

Guess a square number in the vicinity of 1000. Say we start with 900. Then,
- (30)^2 = 900
(31)^2 = 961 .... More towards 1000
(32)^2 = 1024 .... More than 1000
The correct answer is B.
