Find the square root of 97344.1. 3122. 3183. 3084. 3025. None of these

1.	Find the square root of 97344.1. 3122. 3183. 3084. 3025. None of these.
Answer» Correct Answer - Option 1 : 312 Concept used:- Trick to find square root of a number. Method and Calculation:- • Find the unit digit of square root by looking at unit digit of given number. For ✓97344, unit digit must be 2 or 8 • Find other two digits by looking at number formed by first 3 digits. 961 < 973 < 1024 (961 and 1024 are squares of 31 and 32, so remaining part of square root will be 31. • Find the square root from the narrowed down options. ✓97344 = 312 or 318. To find this, we multiply 31 × 32, which is equal to 992 and is more than 973. Hence the smaller of two will be the square root Clearly, ✓97344 = 312

Find the square root of 97344.1. 3122. 3183. 3084. 3025. None of these.

Answer» Correct Answer - Option 1 : 312

Concept used:-

Trick to find square root of a number.

Method and Calculation:-

• Find the unit digit of square root by looking at unit digit of given number.

For ✓97344, unit digit must be 2 or 8

• Find other two digits by looking at number formed by first 3 digits.

961 < 973 < 1024 (961 and 1024 are squares of 31 and 32, so remaining part of square root will be 31.

• Find the square root from the narrowed down options.

✓97344 = 312 or 318. To find this, we multiply 31 × 32, which is equal to 992 and is more than 973. Hence the smaller of two will be the square root

Clearly, ✓97344 = 312
