This lesson introduces exponents, explaining how they represent the number of times a base is multiplied by itself. We'll cover concepts like squared and cubed numbers, and discuss how to express repeated multiplication using exponents (e.g., (a times a times a) becomes (a^3)). We'll practice squaring and cubing numbers, as well as expanding and evaluating expressions such as (25^2), (34^3), and (106^2). This foundational knowledge is essential for advancing in algebra and geometry.
