Find the product. -mnp(3m - 5n 7p)

Answers

If you would like to find the product, you can calculate this using the following steps:

-mnp * (3m - 5n7p) = -mnp * 3m + mnp * 5n7p = -3m^2np + 35mn^2p^2

The correct result would be -3m^2np + 35mn^2p^2.

$-mnp(3m-5n7p)=\n\n-mnp*3m+mnp*5n7p=\n\n-3m^2np+35mn^2p^2\n\n\sf\ ANSWER={\boxed{-3m^2np+35mn^2p^2}$
