What are the coefficients and times of 3 / 5 * m's Square * n's Square? There are unknowns in the molecule, and what can't be solved is the monomial?

What are the coefficients and times of 3 / 5 * m's Square * n's Square? There are unknowns in the molecule, and what can't be solved is the monomial?

The coefficient is 3 / 5
The number of times is four
There is only one term in a monomial, that is, there is no plus or minus sign, only multiplication and division sign
