Answer:

A.
$x=\frac}log55.25}{3log6}$

Explanation:

We are given that

$4\cdot 6^(3x)=221$

We have to find the exact value of x.

To find the exact value of x we will take log on both sides.

6^(3x)=(221)/(4)

Using division property of equality

6^(3x)=55.25

Taking log on both sides of equality

Then, we get

3xlog6=log55.25

Using property :

Using division property of equality

Hence, option A is true.
