Exponents and Exponential Notation

This video tutorial introduces the concept of exponents and demonstrates how to express repeated multiplication using exponential notation. It begins with a real-world problem involving an ant colony whose population doubles each month. The tutorial covers basic multiplication, introduces exponential notation, and provides practice problems. It also explains how to handle negative numbers in exponents and solves the ant colony problem using exponential notation.

What happens to the ant population every month?

• It doubles.

• It remains the same.

• It decreases by half.

• It triples.
