GPREP - is my approach right?

If the prime numbers p and t are the only prime factors of the integer m, is m a multiple of t*p^2?
(1) m has more than 9 positive factors
(2) m is a multiple of p^3

This is how i solved this problem.
m can expressed in terms of p,t.

Qn-is m a multiple of p^2t or it can be put across as can m divided by p^2t

Statement 1) doesn't help.

Statement 2)m is a multiple of p^3 -- this implies that m is divisible by p^3.

Therefore m has a minimum power of three.So, m has to be divisible by p^2t.
