To solve the equation:

$\log(x) = 4$

we need to rewrite this in exponential form. The equation $\log(x) = 4$ means:

$x = 10^4$

Now, calculating $10^4$:

$x = 10000$

So, the solution is:

$x = 10000$

Here are some related questions to explore:

1. What if $\log(x) = 5$? What would $x$ be?
2. How would you solve $\ln(x) = 4$ instead of $\log(x) = 4$?
3. What are some real-world applications of logarithmic equations?
4. How does changing the base of the logarithm affect the solution?
5. How would you solve an equation like $\log(x) + 2 = 5$?

Tip: Remember that $\log(x)$ typically implies base 10 if no base is specified, while $\ln(x)$ implies base $e$.
