To rewrite the logarithmic expression $\log_6 1296 = 4$ in exponential form, you use the definition of a logarithm:

$\log_b a = c \quad \text{is equivalent to} \quad b^c = a$

So, $\log_6 1296 = 4$ becomes:

$6^4 = 1296$

Let me know if you'd like more details or have any questions.

Here are some related questions for practice:

1. Rewrite $\log_2 16 = 4$ in exponential form.
2. Solve $\log_3 x = 5$ for $x$.
3. Convert $2^5 = 32$ into logarithmic form.
4. What is $\log_5 25$ as an exponent?
5. If $7^3 = x$, what is $\log_7 x$?

Tip: When converting between logarithmic and exponential forms, remember that the base of the logarithm becomes the base of the exponent.
