Question

least number that should be subtracted from 15626 to make it as perfect sqauare

urgently needed ​

Answer 1

Answer:

You have to think that for all multiples of 3, the sum of its digits is also equal to a multiple of 3, let’s try it out with 2816 and let’s go down.

2+8+1+6=17

2+8+1+5=16

2+8+1+4=15

We just went down to 2814 so the difference between this numbers is the least number to be subtracted from 2816 in order to make it a multiple of 3.

2816-2814=2

The answer is 2

Step-by-step explanation:

Answer 2

Answer:

√15626= (125)^2+1

so if we subtract 1 from 15626 then resultant number will be perfect square
