Using the Product Rule of Exponents, which states that when you multiply two powers with the same base, you can add the exponents, we can simplify the expression \(1^9 \times 1^8\).
According to the Product Rule:
\[ a^m \times a^n = a^{m+n} \]
In this case, the base \(a\) is \(1\), and the exponents \(m\) and \(n\) are \(9\) and \(8\) respectively.
So, we can add the exponents:
\[ 1^9 \times 1^8 = 1^{9+8} = 1^{17} \]
Thus, the equivalent form is:
- Base = 1
- Exponent = 17
