^{xy}+x

^{2}+y

^{2}= 5 at point (2,0)

I'm confused with finding the derivative with respect to x of e

^{xy}.

this is what I did so far for just this part: e

^{xy}*d(xy)/dx

e

^{xy}*(y+x*dy/dx)

do I need to put the parentheses on here? I thought so because that is the part where I used the product rule. (but probably not, right?)

then for the entire function so far this is what I got:

e

^{xy}*(y+x*dy/dx)+2x+2y*dy/dx=5

am I doing something wrong so far?
