Question

which least number must be added to 7912 to make the sum a perfect square.​

Answer 1

Answer:

9

Step-by-step explanation:

Given that which least number should be added to 7912 to make the sum a perfect square?

Steps.

1. First let us take square root of 7912

 So square root of 7912 is 88 and remainder is 168.

Now 88^2 is 7744. We need to add to 7912 to make it a perfect square. 7744 is less than 7912.

2. So let us consider 89^2 , it will be 7921.

So 7921 - 7912 = 9

Thus when 9 is added to 7912 we get 7921.

Hence 7921 is a perfect square.
