6,241 is a number whose square root is the perfect number. Then this number is multiplied by its square root. The answer is Correct Answer 4,93,039

Calculations:

To find a square root of a perfect square number, follow these steps :

Step 1: Given number is in between of which numbers.  

⇒ 6,241 is between 4,900 and 6,400.

So square root of 6,241 will be between the square root of 4,900 and 6,400 i.e.70 and 80.

Step 2: Predict the number using the unit digit of a number.

⇒ Unit digit of 6,241 is 1.

So, the Square root of a number 6,241’s unit digit will be either 1 or 9.

⇒ A number whose unit digit is 1 or 9 and between 70 and 80 are 71 and 79.

Step 3: Check by nearer value.

⇒ 71’s square will be nearer to 4,900 and 79’s square will be nearer to 6,400.

⇒ 6,241 is near 6,400, so the square root of 6241 is 79.

⇒ Now 6,241 × 79 = 4,93,039. 

Asked value is 4,93,039.
