Applying the Rules of Exponents: Basic Examples

This video tutorial covers the fundamental rules of exponents, focusing on multiplying like bases and exponentiation of a power. The instructor explains these concepts using generic examples and then applies them to solve two example problems. The first problem involves multiplying expressions with like bases, while the second problem deals with exponentiation of a power, including negative bases. The video emphasizes common mistakes and provides strategies to avoid them, ensuring a solid understanding of exponent rules.

Why are the rules of exponents important in algebra and calculus?

• They are only used in geometry.

• They help in solving linear equations.

• They are used to find the roots of polynomials.

• They simplify complex expressions involving exponents.
