Best ResponseYou've already chosen the best response.2ln(x^2 + 3) is a compound function  function within a function so we can write it as f(g(x) where g(x) = x^2 + 3 so derivative of f(g(x) = f'(g)x) * g'(x) = 1/ (x^2 + 3) * 2x = 2x/ (x^2 + 3)  that is f'(x)

Best ResponseYou've already chosen the best response.2i used the standard derivatives D (ln u) = 1/u. and D (x^n) = nx^(n1)
