Well for the first part you just need to write down the inequality

in terms of n and rearrange using standard methods. That shouldn't be too difficult.

Bernoulli's inequality states that

for certain x and r (but those conditions aren't an issue because n is presumably positive).

So here's a hint:

Now have a go at it and let us know if you need further help

Thank you. I was wondering if you could help out with the rearrangement because I've tried so many times and still can't get a result! Thanks

Try multiplying both sides by

and then simplify the LHS
