Answer 1

To correctly develop an expression using the Power Rule of Exponents, we want to look for an expression that can be simplified using the rule, which states that \(a^m \cdot a^n = a^{m+n}\) and \((a^m)^n = a^{m \cdot n}\).

1. **\((-5)^0**: This expression simplifies to 1, but it does not involve application of the power rule.

2. **\((7^8) \cdot (7^{10})**: Here, we can apply the power rule. The exponents can be added together because the bases are the same:
\[
7^8 \cdot 7^{10} = 7^{8+10} = 7^{18}
\]

3. **\(12^9**: This expression does not involve any operation between exponents and cannot be simplified further using the power rule.

4. **\((7^4)^8**: This expression can use the power rule where we multiply the exponents:
\[
(7^4)^8 = 7^{4 \cdot 8} = 7^{32}
\]

From the options, the expression that is correctly developed using the Power Rule of Exponents is **\((7^8) \cdot (7^{10})**.
