Question

\(\sqrt{361}\) = ______

(a) 21

(b) 19

(c) 11

(d) 29

I got this question in my homework.

This question is from Square Root in portion Squares and Square Roots of Mathematics – Class 8

Answer 1

The correct answer is (b) 19

For explanation I would say: If we need to find the square root of number 361 we can subtract first 19 odd numbers which would give us 0. From this we can could that 19=\(\sqrt{361}\). Hence 19 is the correct answer and the others are incorrect.
