the word THAN should have been THEN, AND there should only be one o in the word PROVE.
 
By the Fundamental Theorem of Arithmetic, every composite number has a unique prime factorization.
Therefore the exponent on 3 must be 2 and the exponent on must be 1.

Thank you very much, I'll keep in mind those corrections.
On a test it was given this equation system: 3x5y=45 and 3y5x=75. I only wrote the previous response: if 3x5y=325, then x=2 and y=1, will this response count even if i didn't solve it like a system?
