what is the minimum value of abs(81m-576n+510) as m,n take all integer values?Here,abs is absolute value function (i.e.,if x>0, then abs(x)=x and if x<0,then abs(x)=-x)

• 9*9m-9*64n+9*57-3
  so the minimum value is 3 because 9*57 is 513,so we have to decrease 3 inorder to get 510

• 81m-576n+510
  =>9(9m-64n)+510
  =>9(-57)+510
  =>-3

• try to take common frm 81 and 576......... nd u will get as 9
  i.e (9*9*m-9*64*n) , say this as x
  then we can write as (9x-510)
  then divide 510 by 9 nd u will get approx 56.66
  take two no. 56 and 57, multiply both by 9 and u will get 504 and 513
  for min value take 57=x
  57*9-510=513-510=3 Ans
