Error in p-norm definition, Algebra & Calculus refresher

[AhmetZamanis]

Hi, thanks for putting together & sharing this information source.

I believe there is an error in the p-norm formula, in the Algebra and Calculus refresher:

I think $x_i^p$ should be replaced with $|x_i|^p$. This way, we end up with the L1 norm (Manhattan distance) when p = 1.
