Answer:
The correct answer option is D. 81.
Step-by-step explanation:
We are given the following expression and we are to find the value of x:
[tex] log _ 3 x = 4 [/tex]
We can inverse [tex] log _ 3 x [/tex] and re-write it as [tex]3^x[/tex].
Doing that, we will raise both the sides of the equation to the power of 3 to get:
[tex] 3 ^ { log 3 x } = 3 ^ 4 [/tex]
x = 81
