1. **State the problem:** Simplify or analyze the expression $$\frac{(a - 3)^{1 - \sqrt{2}}}{a + 2}$$ where $a$ is a variable.
2. **Recall the rules:**
- When you have an expression with an exponent like $x^m$, it means $x$ multiplied by itself $m$ times.
- The exponent here is $1 - \sqrt{2}$, which is an irrational number since $\sqrt{2}$ is irrational.
- The denominator is $a + 2$, which cannot be zero (so $a \neq -2$).
3. **Rewrite the expression:**
$$\frac{(a - 3)^{1 - \sqrt{2}}}{a + 2} = \frac{(a - 3)^1}{(a - 3)^{\sqrt{2}}(a + 2)} = \frac{a - 3}{(a - 3)^{\sqrt{2}}(a + 2)}$$
4. **Simplify the numerator and denominator:**
$$= \frac{a - 3}{(a - 3)^{\sqrt{2}}(a + 2)} = \frac{\cancel{a - 3}}{(a - 3)^{\sqrt{2}}(a + 2)} \text{ only if } a - 3 \neq 0$$
Since $a - 3$ in numerator and denominator are not the same power, we cannot cancel directly. So the expression remains as is.
5. **Final expression:**
$$\frac{(a - 3)^{1 - \sqrt{2}}}{a + 2}$$
6. **Domain restrictions:**
- $a \neq -2$ (denominator zero)
- $a - 3 > 0$ if we want real values for the irrational exponent (since fractional powers of negative numbers are not real).
**Answer:** The expression is $$\frac{(a - 3)^{1 - \sqrt{2}}}{a + 2}$$ with domain $a > 3$ and $a \neq -2$.
