How to foil when there is an exponent on one of the parenthesis?

For example, (0.862 - x) (0.373 - 3X)^3.

Thanks
I believe you would expand the second bracket because of the exponent:



(0.373 - 3X) x (0.373 - 3X) x (0.373 - 3X)



so you FOIL the first 2 sets of brackets. Take the newly found answer



(0.139 - 2.238 9x^2) (0.373 - 3x)



FOIL the above and then take that answer and FOIL it with (0.862 - x)



(*new answer*) (0.862 -x )



Make sure I did it right and find your own answer :)
You don
