We went over homework that I sent Sam on simplifying equations with negative exponents. Then we learned that the complement of a set is the set that includes all the elements of the universal set not present in the given set. Next we practiced using the various properties to simplify radical expressions. We reviewed how to multiply by the conjugate to remove a radical from the denominator of a fraction. Then we focused on various algebraic and geometric applications that involve using, simplifying, and combining radical expressions. Then we applied the Pythagorean Theorem to find the hypotenuse of triangles.
