Answer:

[tex]x=0[/tex]

Step-by-step explanation:

We have been an rational expression [tex]\frac{x-4}{4x}[/tex]. We are asked to find the value of x for which our given expression is undefined.

We know that a rational expression is undefined when its denominator becomes zero. So find such value of x for our given expression, we will equate denominator with 0 and solve for c as:

[tex]4x=0[/tex]

[tex]\frac{4x}{4}=\frac{0}{4}[/tex]

[tex]x=0[/tex]

Therefore, when x is equal to 0 our given expression will be undefined.
