Best ResponseYou've already chosen the best response.0Which term would you factor out? Because you can take out 2^2n or 2^n1. Which one should you take out? Or its just random \[\huge\frac{2^{2n}2^{n1} }{ 2^{n}2^{1} }\]

Best ResponseYou've already chosen the best response.0for the numerator it would be \[\huge2^{2n}(1  2^{n1})\] Would it?
