1.	Find the square root of 364816.1. 5942. 6043. 6064. 6145. None of these.
Answer» Correct Answer - Option 2 : 604 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 ✓364816, unit digit must be 4 or 6 • Find other two digits by looking at number formed by first 4 digits. 3648 is more than 3600 (60²) and less than 3721 (61²), so first two digit of square root will be 60 • Find the square root from the narrowed down options. ✓364816 = 604 or 606. To find this, we multiply 60 × 61, which is equal to 3660 and is more than 3648. Hence the smaller of two will be the square root Clearly, ✓364816 = 604

Answer» Correct Answer - Option 2 : 604

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 ✓364816, unit digit must be 4 or 6

• Find other two digits by looking at number formed by first 4 digits.

3648 is more than 3600 (60²) and less than 3721 (61²), so first two digit of square root will be 60

• Find the square root from the narrowed down options.

✓364816 = 604 or 606. To find this, we multiply 60 × 61, which is equal to 3660 and is more than 3648. Hence the smaller of two will be the square root

Clearly, ✓364816 = 604
