1. The problem is to simplify the expression $(-7)^0$ and express the answer with positive exponents. 2. The rule for any nonzero number raised to the power of zero is: $$a^0 = 1 \quad \text{for} \quad a \neq 0$$ This means any number except zero raised to the zero power equals 1. 3. Applying this rule to $(-7)^0$: $$(-7)^0 = 1$$ 4. Since the result is already a positive exponent expression (1 can be considered as $1 = 1^1$), the simplified answer is: $$1$$ Therefore, the simplified expression is 1.
