What expression is rational to 01.05 MC?

To determine what expression is rational to 01.05 MC, we need to understand that rational expressions consist of a ratio of two polynomials. For example, a rational expression could be ( \frac{2x + 3}{x - 1} ) or ( \frac{x^2 - 4}{x + 2} ). Specifically, if "01.05 MC" refers to a specific quantity in a context, we would need more details about that context to provide a precise rational expression.
