In this lesson about square roots, Professor Perez teaches us about perfect squares and how to compute the square root of non-perfect squares using a calculator. He also introduces the Pythagorean theorem and how to use it to solve right triangle problems. Finally, he teaches us how to simplify expressions with square roots and how to add and subtract them. By the end of the lesson, we are able to confidently calculate square roots and apply this knowledge in real-world scenarios.
