Question

2. Find the smallest number which when
subtracted from following numbers will
make them perfect squares.​

Answer 1

Answer:

4 must be subtracted from 5480 to make it perfect square that is 5476. So if we subtract 2 from 1158, it will become 1156 which is perfect square of 34. So if we subtract 3 from 2119, it will become 2116 which is perfect square of 46. Hence 3 must be subtracted from 2119 to make it perfect square that is 2116.

Answer 2

Step-by-step explanation:

We know that the nearest perfect square to 200 is 196.

196 is a perfect square of 14

Now we have to find a number when subtracted from 200 we get 196.

200 - a = 196

Second question

Similarly the nearest perfect square to 175 is 169. Which is a perfect square of 13.

Now we have to find a number when subtracted from 175 to get 169

175 - a = 169

a = 175 - 169

a = 6
