Answer
A complex rational expression is a rational expression where the numerator and / or the denominator are also rational expressions. Example: \(\frac{\frac{5}{x} + 3}{1 - \frac{2}{x}}\).
1Step 1: Defining Complex Rational Expression
A complex rational expression is a fraction where the numerator and / or the denominator are also fractions. They can be thought of as a fraction divided by another fraction or multiple fractions. It extends the idea of rational numbers (which are simply fractions) to expressions that contain polynomials.
2Step 2: Example of Complex Rational Expression
Consider an example of a complex rational expression: \(\frac{\frac{5}{x} + 3}{1 - \frac{2}{x}}\). This is a complex rational expression because the numerator \(\frac{5}{x} + 3\) and the denominator \(1 - \frac{2}{x}\) both contain rational expressions or fractions.
