Induction Inequality Proof Example 3: 5^n + 9 less than 6^n

Another viewer-submitted question. Inequality proofs seem particularly difficult when they involve powers of n, but they can be managed just like any other inequality given the right algebraic techniques! I had to stop and start this video a couple of times due to the cleaner walking into my staffroom while I was shooting. Hopefully it doesn't interrupt the flow of the explanation too much!
