  hi shiva
  the answer would be 4.
  reason
  from 1 to 10 there are 3, 6 & 9 which are divisible by 3.
  arrange them as
  3=3^1
  6=2*(3^1)
  9=3^2
  add the power terms and that will be the highest power ie (1+1+2)=4.

  The answer I think is 5.
  5 is the highest number between 2,3,4 and 5. 5 can divide 10 completely.But it will have decimals.
  If we don't want decimals then the answer is 2.
  
  But my final answer is 5.
