Knowledge Notes:

To solve the given problem, we apply the following knowledge points:

1. Multiplication of Fractions: To multiply fractions, we multiply the numerators together and the denominators together.

2. Simplifying Fractions: This involves canceling out common factors between the numerator and the denominator.

3. Factoring: This is the process of breaking down numbers into their constituent prime factors or common factors.

4. Cancelation: When a factor appears in both the numerator and the denominator, it can be canceled out from both, simplifying the fraction.

5. Exponent Rules: When we have the same base with exponents in both the numerator and the denominator, we can subtract the exponents if we are dividing.

6. LaTeX Formatting: Mathematical expressions are formatted using LaTeX syntax to clearly present the problem-solving process.

By applying these principles, we can simplify the given algebraic fraction to its simplest form.
