As always a very seamless solution and well worked out. What puts Master T ahead in his lecture hall is his not jumping a step hoping students or listeners might follow along but goes step by step that my 10 year old could follow through. You are a GENIUS !!!

Germany Math Olympiad: (√120 + √8)/(√120 - √8) =?
(√120 + √8)/(√120 - √8) = [(√8)(√15 + 1)]/[(√8)(√15 - 1)] = (√15 + 1)/(√15 - 1)
= [(√15 + 1)²]/[(√15 - 1)(√15 + 1)] = (15 + 2√15 + 1)/(15 - 1) = (8 + √15)/7
