While we did some work with dividing radical expressions on Monday, we expanded on it today to make the observation that, in general, we try not to leave any radicals in the denominator of an expression. The process of fixing this is called rationalizing, and so your homework for tonight is HW 4.3 – Rationalizing Denominators. As usual, you can find the notes here and a video with some extra examples here.
