Maths Problem
How do you expand quadruple brackets. I have searched on youtube but there are only videos of how to expand triple brackets.
E.g. (x+y)^4
E.g. (x+y)^4
Not sure what level you are currently studying but my first guess is to suggest if you are familiar with binomial expansion? This is much quicker.
Otherwise, recall on expanding triple brackets where you expanded two brackets first then expanded the third bracket.
Four brackets is the same: Expand two then the third then the fourth. Take it step by step.
