You have to do the exponents first before multiplying anything else..

Do i subtract the exponents?
Noo, just do the exponent first, because what you did will give you a totally different answer.. lemme show you what I mean: If we did what you did: \(\large 4*3^3 \) would give \(\large 12^3 \) which is \(\large 1728\) .. As opposed to \(\large 4*(3^3) \) which should be \(\large 4*27 \) which is \(\large 108\)
See the difference in just the first term?
Ah, I see what you did.

Yes, now just finish multiplying and whatever else you need, you should get the right answer.
