Find the square root of 961.(a) 31(b) 39(c) 29(d) 21The question was posed to me during an online interview.My query is from Finding Square Roots in division Squares and Square Roots of Mathematics – Class 8 |

Answer» CORRECT option is (a) 31 To explain I would say: Here the trick of checking the last DIGIT of square and square ROOTS fails because if any square has 1 in one’s place the square ROOT can have either 1 or 9 in its ones place. So here we calculate the square root. After CALCULATING we get the square root as 31. |
