We use a problem from the ISI BStat BMath Entrance exam 2015 which involves finding the minimum value of an expression, demonstrating algebraic manipulation without AM-GM inequality.
We look at the relationship between AM and GM and use the fact that the arithmetic mean is always greater than or equal to the geometric mean. We also explore a geometric interpretation of the AM-GM inequality using the example of lengths forming a circle's diameter.
