To solve the equation \( 10 \log(10^5) = 10x \), we can start simplifying the left side.
First, we know from the properties of logarithms that:
\[ \log(10^5) = 5 \]
because the logarithm of a base raised to a power is equal to that power.
Substituting this back into the equation gives us:
\[ 10 \cdot 5 = 10x \]
which simplifies to:
\[ 50 = 10x \]
Now, we can solve for \( x \) by dividing both sides by 10:
\[ x = \frac{50}{10} = 5 \]
So, the final answer is:
\[ \boxed{5} \]
