Answer:
E
Explanation:
well, process of elimination
0.018 will be 18/1000 = 9/500
Its 10+20= 30 and 10++20=30
<u>Given</u>:
The given expression is 
We need to determine the value of x using either base - 10 or base - e logarithms.
<u>Value of x:</u>
Let us determine the value of x using the base - e logarithms.
Applying the log rule that if
then 
Thus, we get;

Applying the log rule,
, we get;

Expanding, we get;

Subtracting both sides by
, we get;

Subtracting both sides by
, we get;

Taking out the common term x, we have;



Thus, the value of x is 
12X is the period of what is the period of f : R→R, f(x) = tan(x 3)?
