To solve the equation \(10 \log x = 1107\), we will first isolate \(\log x\):
\[ \log x = \frac{1107}{10} = 110.7 \]
Next, we convert the logarithmic form to its exponential form:
\[ x = 10^{110.7} \]
Now, let's analyze the responses you provided:
- \(7\)
- \(10^7\)
- \(-7\)
- \(10^{-7}\)
The value \(10^{110.7}\) does not match any of the given options. Therefore, none of the provided responses are correct. The value of \(x\) is \(10^{110.7}\).
