1. The problem statement, all variables and given/known data Determine the derivative of f(x)=√(7+√x^3) 2. Relevant equations Chain rule: f(x)=fog(x) f'(x)=f'(g(x)) x g'(x) 3. The attempt at a solution f(x)=√(7+x^(3/2)) f'(x)=((½)x^(-½))(7+x^(3/2))((3/2)x^(½)) =(3.5x^(-½)+½x)((3/2)x^(½)) =5.25x^0+¾x^½ =5.25+¾x^½ That's as far as i got and i feel like it is completely wrong. Any guidance and help is very much appreciated! Thanks in advance.
