Limits of implicit functions

Question

I saw a limit today that it was weird because I never saw a implicit function limit.

Can anybody help me with this?

$$\lim_{(x,y)\to (2,2)} \frac{x^3-y^3+2-2}{(x-y)^2-2}$$

$$\lim_{(x,y)\to (e,1)} \ln(x^2y^2)$$

Answer 1

for the first limit we have $$\frac{8-8}{(2-2)^2-2}=\frac{0}{-2}=0$$
