To begin with, we need to rationalize the denomenator. To do so, we multiply that by \(3 + 2\sqrt2\). (this is an excellent website for rationalizing the denominator: https://www.chilimath.com/lessons/intermediate-algebra/rationalizing-the-denominator/)
Anyways, multiply the top and bottom by \(3+2\sqrt2\). This will give you \(88+54\sqrt{2}\).
