Question

While taking square roots we cannot include _____ numbers.

(a) prime

(b) natural

(c) whole

(d) negative

I got this question in a job interview.

My query is from Square Root in chapter Squares and Square Roots of Mathematics – Class 8

Answer 1

The correct option is (d) negative

For explanation I would say: While taking square roots we have to take care that we cannot have real roots for negative numbers. The roots of negative numbers are imaginary. Hence the correct option would be negative and the others are wrong.
