Answer 2

Answer:

There is a simple method for all such problems that can be used in all sorts of exams...

Step-by-step explanation:

1. Take the square root of the given number

given no. is 7190, so the square comes out to be 84.8 and so on (refer above pic)...

2. see between which two natural no.s the square root lies....

in the question 84.8 lies between 84 and 85.

3. Depending on the question, add or subtract the difference between the previous no. or latter no.

in the question you are told to add a number to get the next square which is 85... so 85 square is 7225. Subtract: 7225-7190= 35 that's your answer

of you were told to subtract the smallest no. from 7190 to make it a perfect square, the answer would be 7190-84square

of you were told to subtract the smallest no. from 7190 to make it a perfect square, the answer would be 7190-84square =7190 - 7056

=134

Hope it helps

All the best and don't forget your promise as mentioned in the question
