SUMMARY
The function g(x,y) = (xy)^(1/3) is continuous at the point (0,0). When evaluating the limit as (x,y) approaches (0,0), the limit L equals 0, which matches the function's value at that point. Despite this, graphical representations in tools like Maple may incorrectly suggest a discontinuity along the axes due to limitations in handling cube roots. The conclusion is that the function is indeed continuous, and further analysis is required to determine its differentiability at (0,0).
