Answer 2

Answer:

We have to add 4 to get a perfect square

Step-by-step explanation:

Do long division method for finding root

The number is 11660

Take 116 separate and 60 separate

The divisor is 10 because nearest square of 116 is 100

Now the quotient is 10.

Double the number in the quotient = 10 * 2 = 20

Now 20 is the divisor.

Take the remaining 60 down now the dividend is 1660.

Now we have to do :-

201 * 1 = 201 It wont come

202 * 2 = 404

203 * 3 = 609

204 * 4 = 816

205 * 5 = 1025

207 * 7 = 1449

208 * 8 = 1664 It will come

If you subtract 1660-1664 = -4 is the remainder.

Here remainder is 4 so we have to add 4 to the number to get a perfect square
