The equation you provided, \( x^n + y^n = z^n \), is central to a famous problem in number theory known as **Fermat's Last Theorem**. This theorem states that there are no positive integer solutions to this equation when \( n > 2 \) and \( x, y, z \) are non-zero integers.

Here’s a summary of key points related to Fermat's Last Theorem:

1. For \( n = 2 \), the equation becomes \( x^2 + y^2 = z^2 \), which is known as **Pythagoras' theorem**. This equation does have solutions, known as Pythagorean triples (e.g., \( 3^2 + 4^2 = 5^2 \)).

2. For \( n > 2 \), Fermat’s Last Theorem claims there are no whole number solutions for \( x, y, z \), other than trivial cases (where one of the numbers is zero).

3. The theorem was famously conjectured by Pierre de Fermat in 1637, but it remained unproven until Andrew Wiles provided a complete proof in 1994.

4. Fermat originally claimed to have a proof that was "too large to fit in the margin" of his book, but no such proof was ever found, leading to centuries of mathematicians attempting to prove it.

5. Wiles’ proof uses advanced concepts from algebraic geometry and modular forms, far beyond elementary methods.

Here are five related questions:
1. What are Pythagorean triples, and how are they derived?
2. What is the general form of the proof Andrew Wiles used for Fermat’s Last Theorem?
3. How does Fermat's Last Theorem relate to modern number theory?
4. Can Fermat’s Last Theorem be extended to complex numbers or rational solutions?
5. How does the equation behave when one or more variables are non-integers?

**Tip:** Fermat's Last Theorem is a classic example of how simple-looking problems can lead to profound mathematical discoveries.
