A perfect square is the number which is exactly equal to multiplication of 2 equal integers twice.
A perfect cube is the number which is exactly equal to multiplication of 2 equal integers thrice.
As 200 cannot exactly meet the above criteria, it is neither a perfect cube nor a perfect square.
200=14.1421*14.1421
As 14.1421 is not a integer 200 is not a perfect square.
200=5.84803*5.84803
As 5.84803 is not a integer 200 cannot be a perfect cube.
