Could you guide and explain this to me step by step?
**Problem Statement:**
Determine whether the limit exists. If so, find its value.

**(a)** 
\[ \lim_{(x,y) \to (0,0)} \frac{x^4 - 10y^4}{x^2 + 4y^2} \]

**(b)** 
\[ \lim_{(x,y) \to (0,0)} \frac{x^{10}y}{x^{10} + y^2} \]

These problems involve evaluating the limits of multi-variable functions as the variables approach the origin (0,0). To determine whether the limit exists, approaches such as substituting specific paths (e.g., along x-axis or y-axis) or polar coordinates transformation can be used.
