Question

Multiply. −3/7xy(−35x^3y2)

Answer 1

So I believe this is your question?
$- \frac{3}{7} xy(-5 x^{3} y^{2} )$
Correct?

In solving this problem, just distribute each number or letter over to what's inside the parentheses. Multiply you numbers together first: $\frac{3}{7} *-35=3*-5=-15$ (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: $x* x^{3} = x^{4}$

Finally multiply your y's together: $y* y^{2} = y^{3}$

Now just put all of them together like this:
$-15x^4y^3$
This should be your final answer.
