Question

what is the least number to be added to 2530 to make it a perfect square ?

Answer 1

1st we will find the square root of 2530 and then get the remaining value.

Hence we get the remaining no. as 30 and in the quotient area as 50(approx.....took out in my rough nb)

This means that if we subtract 30 from 2530 we will get the square of 50.

Now,  50 whole square = 2500

         Hence the no. to added will be the 2530 subtracted from the square of next no.

Next no.= 51 ....51 whole square= 2601

hence no. to be added= 2601-2500=101

thanks hope it helps ..pls mark as brainliest.
