HELP!!
This is a link to a rooted tree:
Question: Use the rooted tree below to perform a pre-order traversal of the expression. I came up with:
(x+2^3)*y-(3+x)-5 I need to know if this is right; or should it be
(x+2)^3 *y-(3+x)-5

what?

preorder traversal sort of like (x+2) for the first order; not sure about the second ^3; then the next order is (*) times so it would be (x+2)^3 * (y-3).... something like that.
