Multiplying rational expressions

The video tutorial explains how to multiply rational expressions by multiplying numerators and denominators directly. It emphasizes the importance of simplifying expressions using exponent rules. The tutorial demonstrates the process step-by-step, including rearranging variables and applying exponent subtraction. The final result is presented in a simplified form, with a focus on writing higher degree terms first.

What is the first step when multiplying rational expressions?

• Subtract the numerators from the denominators.

• Add the numerators and denominators.

• Divide the numerators by the denominators.

• Multiply the numerators and denominators directly.

When simplifying rational expressions, what should you do with a negative exponent in the denominator?

• Leave it as it is.

• Convert it to a positive exponent in the numerator.

• Convert it to a positive exponent in the denominator.

• Ignore the exponent.
