In this lesson, we learn how to evaluate radical expressions of integers using a graphing calculator. The teacher demonstrates how to enter the expressions into the calculator and emphasizes the importance of using parentheses to avoid incorrect answers. Through examples, we see how to approximate irrational numbers and round to the desired number of decimal places. This lesson sets the foundation for more complex radical expressions in later chapters, making it essential to have a graphing calculator.
