I simplify expressions like root 180 and demonstrate how to rationalize denominators. I also explain how to approach ratio problems using both parts and fractions, ultimately leading to the same answer. Additionally, I tackle a geometric sequence problem to find the common ratio. I encourage you to follow along with the calculations and practice similar problems for better understanding.
