Question

The smallest number that should be added to or subtracted from the sum of
squares of 9 and 10 to make it a perfect square is​

Answer 1

Answer:

9^2 + 10^2 = 81+100 = 181

NEAREST SQUARE NO. 196

SO 15 SHOULD BE ADDED

Answer 2

Answer:

15 AND 12

Step-by-step explanation:

Sum of squares of 10 and 9

= 100 + 81 = 181.

Smallest number to be added to make 181 a perfect square = 181 + 15 = 196 = 14².

And, smallest number to be subtracted to make 181 a perfect square = 181 – 12 = 169 = 13².
