I get it... Just treat it like a normal variable. You'll see it. Eltu. Five foot rule.

That is not what I meant by vectors, yes they could be variables but they could also represent different dimensions in a geometrical plane. It is very common to assign the letter i for yaxis. You could assign any symbol you wanted to I guess to represent any dimension.
Both sides have 9 units in one direction (I will call it width), one has 7 units in another (I could call height), and the the other size has 21 units in the third dimension (depth). To solve this we would have to use the cross product (sometimes called the vector product) since we are using vectors in three dimensions (which I am too lazy to do as I am also too tired of math problems). We could actually verify that one vector is larger than the other. EDIT: or if they're just variables then I'm over thinking it but it would sitll have a specific answer Last edited by Banefull; 11042010 at 06:43 PM.

They might make sense but they wont be the answer Eltu is looking for.

Do we know if Eltu made up this problem? He could have copied it from somewhere else. And if it was by Eltu, how do you know what his original intent was? You =/= Eltu.
This belongs in the debate forum imho.

Not imaginary numbers, here i is just equivalent to x
This goes well with the equation Quote:
