Exponent Rules and Simplification Techniques

The video tutorial explains how to simplify a fraction raised to a power using the power to power exponent rule. It demonstrates the process with an example, showing how to multiply exponents for both the numerator and denominator. The tutorial also presents an alternative method for simplification by expanding the expression and multiplying the factors. The key takeaway is the importance of understanding and correctly applying the exponent rules to simplify expressions efficiently.

• Add the numerator and denominator.

• Divide the numerator by the denominator.

• Subtract the denominator from the numerator.

• Raise both the numerator and denominator to the power.

According to the power to power exponent rule, what should you do with the exponents?

• Subtract the exponents.

• Divide the exponents.

• Multiply the exponents.

• Add the exponents.
