Best ResponseYou've already chosen the best response.0This seems fun, ok so you know that \[y^2 = y \times y\] \[y^5 = y \times y \times y \times y \times y\] right? The exponent just means you multiply it by itself that many times, does that make sense so far?

Best ResponseYou've already chosen the best response.0Ok, so when we talk about areas we have 2 dimensions that would mean we have something squared, when we talk about volume we have 3 dimensions so we cube it, let me draw what I mean. dw:1438982740847:dw so A here represents area and we know to get area of a square we write it as \[a^2 = a \times a~~~~14^2 = 14 \times 14\] now we have a cube and to find it's volume, we deal with 3 dimensions so it looks as such dw:1438982814212:dw notice all the dimensions in a cube are the same so we have volume as \[V =a^3\] so what can we conclude our answer to be? (I know this might be a lot at once, but I hope it helps you understand)

Best ResponseYou've already chosen the best response.0Good we have \[14 \times 14 \times 14\] but your question asks for it in exponential form, so that will be?

Best ResponseYou've already chosen the best response.0by the way 63 is 6 powerd by 3 and you have to simplify the answer

Best ResponseYou've already chosen the best response.0Not quite \[216+5(2)\] this is what we have, 5(2) just means multiply
