Answer:
B. [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given expression is,
[tex]\frac{3x}{1-3x}[/tex]
Which is a rational expression ,
Since, the exclude value of a rational expression are the values for which denominator = 0,
Here, the denominator = 1 - 3x
If 1 - 3x = 0,
[tex]\implies -3x = - 1 \implies x = \frac{1}{3}[/tex]
Hence, the excluded value of the given expression is [tex]\frac{1}{3}[/tex]
Option B is correct.
