hmm.. alright, point taken.. so how do I go about this then?

but it divides it into a multiple of 3. That's my point

we start out by assuming that a|3c is correct, therefore a has to be a multiple of 3, if it divides 3c

Alright, I got it If a|3c then a is a multiple of 3 then b is also a multiple of 3, as a divides it therefore a|b+c = b/a + c/a and thus a|c therefore a|3c

If a divides b, and a divides b+c then a divides 3c. How do I go forward with this? This is what I've done so far: suppose a|b and a|b+c then b = an for some integer n and c = am for some integer m ∴ b+c = an+am = a(n+m) = ak for some integer k but I...

Sorry, not really. What values do I put in for for \hat{i}? And what's the \hat{n}? And do I pull E out of the integration as a constant? Then integrate da just to a? I'm sorry, I just got into this class two weeks late, and this is due tomorrow. But I'm going to spend this week catching up.

An E field exists in a region of space and it can be described by: \bar{E} = \hat{i}xy^2 Calculate the flux through a cube of size 1.0m, with one end extending into the positive x,y and z directions. Find the charge enclosed. I have no idea how to start this? can someone point me in...
