Why do this problem?
The numerical examples should prompt learners to formulate and prove a more general statement and then apply it to these special cases. Going from the particular to the general in problem solving is an important skill for a mathematician.

Inequalities play a big role in advanced mathematics and mathematical research and learners in school will benefit from experience of working with inequalities.

They need to know the Binomial Theorem and the formula for the exponential series and then the problem gives experience of applying these formulae and of proof by mathematical induction.

Possible approach
The first part could be a lesson starter or homework in preparation for a lesson or you could do the first part as a class and set the two numerical examples to be done independently.

Key questions
How do the numerical examples relate to $(1 +\frac{1}{n})^n$?
