Answer 5

Whenever you have a \(\sqrt{ \quad }\), you want to factor stuff out. Start by trying to divide by 2, 3, 5, 7, 9, ... basically try to divide out prime numbers. If you have something like \(\sqrt{2\times 2\times 3243} \) you can pull out the \(2\) since: \[\sqrt{2\times 2\times 3243} = \sqrt{2\times 2} \times \sqrt{3243} = 2\times \sqrt{3243} \]
