Answer:
\(x=0\)
Step-by-step explanation:
We have been an rational expression \(\frac{x-4}{4x}\). 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:
\(4x=0\)
\(\frac{4x}{4}=\frac{0}{4}\)
\(x=0\)
Therefore, when x is equal to 0 our given expression will be undefined.
