You're answers so far are all correct.
With the cake problem though...remember that for the upper (top of each layer) surface area you only need to calculate one thing - the upper area of the biggest tier. Imagine looking at the cake from directly above. You see all of the top layer, a ring of the second, a ring of the third, etc. If you smushed it all it would be a single layer equal to the bottom. If you understood that it makes it easier.

Yes, but if I'm actually icing it, I need to put the icing on in those volumes at those times
Good point though. Shoulda thoughta that. I'm afraid I don't understand what this one is asking: Quote:

Whoops. My mistake. If x^2 + 1/(x^2) = 7 and x is greater than 0, find x^5 + 1/(x^5)
