Question

what would be added to 7912 to make the sum a perfect square?

Answer 1

Answer:

9

Step-by-step explanation:

• Given what should be added to 7912 to make the sum a perfect square?

• 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.

• 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.

The least number to be added to 7912 is 9 which makes the sum a perfect square.

Answer 2

Answer:

9

Step-by-step explanation:

Doing the long division method we get 168 as remainder and 88 as quotient.

The remainder is 168.hence 88²<7912.

The next perfect square number is 89²=7921>7912.

Hence the number to be added is 7921-7912=9.

Therefore 9 must be added to 7912 to get a perfect square.

Hope this answer helps.
