#2. Among other things, Al-Karaji worked with combinations of irrational square roots, or \"surds\". There is an equation in our textbook which states $\sqrt{8} + \sqrt{18} = \sqrt{50}$. Show this equation is true, using two different methods: (i) Square both sides of the equation and then obtain an obviously true statement. (ii) Reduce each radical quantity (pulling out perfect squares), thus obtaining a sum which also is obviously correct. (Note: using a calculator to approximate the square roots is not the way to do this problem.)
