Exploring Radical Equations and Exponential Relationships

This video tutorial covers the conversion between radicals and exponents, including common conversions like square roots and cube roots. It explains how to handle negative exponents and provides examples of expressing exponential expressions as radicals. The tutorial also demonstrates the reverse process of converting radicals to exponents. Finally, it addresses solving radical equations, emphasizing the importance of isolating radicals and checking solutions.

What is the rule for converting an exponent to a radical?

• Power over root equals root of power

• Root over power equals power of root

• Power equals root times exponent

• Root equals power times exponent
