Final answer:
The rational expression equivalent to 4/x-3 is 4/(x-3).
Step-by-step explanation:
The rational expression equivalent to 4/x-3 is 4/(x-3).
To convert this expression into an equivalent rational expression, we simply need to place the entire denominator x-3 inside the parenthesis with 4 as the numerator. This ensures that the whole expression is divided by x-3.
For example, if we have the expression 5/x, the equivalent rational expression would be 5/(x-0).
