Best ResponseYou've already chosen the best response.1Please use parentheses to write what you intend. In your #1, you have written \(\sqrt{5} + \dfrac{\sqrt{3}}{\sqrt{5}}  \sqrt{3}\). I'm guessing this is not what you intended. In what I suspect you intended, multiply numerator and denominator separetely by \(\sqrt{5}+\sqrt{3}\) and see what magic happens, especially in the denominator.

Best ResponseYou've already chosen the best response.1SO CLOSE!!!! That's \(8+2\sqrt{15}\) and then you have a common factor in numerator and denominator that can help to simplify a little more. Excellent work. You're getting it.
