To simplify \(10^{-4} \cdot 10^{5}\), you would add the exponents:

\[
10^{-4} \cdot 10^{5} = 10^{-4 + 5} = 10^{1} = 10
\]

Now, to evaluate \(1 \text{ tenth}^{-1}\):

The term "tenth" represents \(10^{-1}\), so:

\[
1 \text{ tenth}^{-1} = 1 \cdot (10^{-1})^{-1} = 1 \cdot 10^{1} = 10
\]

Therefore, we can see that:

\[
10^{-4} \cdot 10^{5} = 10 = 1 \text{ tenth}^{-1}
\]

So, yes, \(10^{-4} \cdot 10^{5} = 1 \text{ tenth}^{-1}\) is correct.
