Answer:
9 is not a cube number.
It is a square number.
If we prime factorise it then,
√(9)= √(3*3)
There is only pair of two numbers. If there was other 3 in the factors of 9 then 9 would be a cube number. BUT IT NOT POSSIBLE.

Answer:-
No, as 9=3x3 and there is no natural number which multying by taking three times gives 9. We can see also that 2x2x2 = 8 and 3x3x3 = 27
This shows that 9 is not a perfect cube.
