Best ResponseYou've already chosen the best response.1Noo, 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 \(\large 108\)
