number that should be substracted from
999 to get a perfect square).​

Answer 1

Answer:

38 should be subtracted

Step-by-step explanation:

The largest 3 digit number is 999..but it is not a perfect square..

30^2=900

31^2=961

32^=1024

we see that 961 and 1024 are nearer to 999..but asked to find 3digit perfect square,hence we consider 961 only..

hence 999-961=38

so 38 must be subtracted from 999 to get largest 3digit perfect square
