Answer:

$\log_4(5x+4) = 9$

Explanation:

When we take the log of both sides of the equation:

4^9 = (5x+4)

we get:

$\log_4(4^9) = \log_4(5x+4)$

$\boxed{9 = \log_4(5x+4)}$

We can recognize this as option D.

_____

Note:

The logarithmic function outputs the exponent to which the base must be raised by to get the value in the function.

$\log_\text{base}(\text{value})$

In this problem, 4 has to be raised to the exponent 9 to get
4^9 .
