Question

Find the value of x. log 3 x=4

Answer 1

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:

$log _ 3 x = 4$

We can inverse $log _ 3 x$ and re-write it as $3^x$.

Doing that, we will raise both the sides of the equation to the power of 3 to get:

$3 ^ { log 3 x } = 3 ^ 4$

x = 81
