So I believe this is your question?
[tex]- \frac{3}{7} xy(-5 x^{3} y^{2} )[/tex]
Correct?
In solving this problem, just distribute each number or letter over to what's inside the parentheses. Multiply you numbers together first: [tex] \frac{3}{7} *-35=3*-5=-15[/tex] (If you don't know how I did that step just let me know and I can explain that for you.)
Next multiply your x's together: [tex]x* x^{3} = x^{4} [/tex]
Finally multiply your y's together: [tex]y* y^{2} = y^{3} [/tex]
Now just put all of them together like this:
[tex]-15x^4y^3[/tex]
This should be your final answer.
