Understanding Powers and Exponents

The video tutorial explains the rule for finding a power to a power, which involves keeping the base and multiplying the exponents. It provides examples with different bases and exponents, demonstrating how to apply the rule and evaluate the results. The tutorial also shows the expanded form of a power to a power to clarify the concept.

What is the basic rule for finding a power to a power?

• Keep the base and multiply the exponents

• Add the exponents and change the base

• Subtract the exponents and keep the base

• Divide the exponents and change the base
