In a
Perfect Cube the all the numbers of factors should have pair of three.
Question - Type 2 - Is 200 is a perfect cube ?

2*2*2*
5*5
Since 5*5 are only two pair, therefore
200 is not a perfect cube.
Question - Type 3 - With what number 200 is to be multiplied to make it perfect cube
Answer - 3- Make the factors
200=
2*2*2*
5*5
Since 5*5 are only two pair,
therefore 200 must be multiplied with 5 to make it a perfect cube.
i.e. 200*5=1000=10*10*10
Now this is a perfect cube and the cube root is 10.
