Comentários (5) Será aplicada algumas propriedades de derivação de funções exponenciais:

$f'(x)=7^{\frac{x+1}{\ln(x+1)}} \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{x+1}{\ln(x+1)}.\ln(7)]' \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[(\frac{x+1}{\ln(x+1)})'.\ln(7)+(\frac{x+1}{\ln(x+1)}).\ln(7)'] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[(\frac{x+1}{\ln(x+1)})'.\ln(7)+(\frac{x+1}{\ln(x+1)}).0] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{(x+1)'\ln(x+1)-(x+1)\ln(x+1)'}{[\ln(x+1)]^2}.\ln(7)]$

$f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{1.\ln(x+1)-(x+1).\frac{1}{(x+1)}.(x+1)'}{[\ln(x+1)]^2}.\ln(7)] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{\ln(x+1)-(x+1).\frac{1}{(x+1)}.1}{[\ln(x+1)]^2}.\ln(7)] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{\ln(x+1)-(x+1).\frac{1}{(x+1)}}{[\ln(x+1)]^2}.\ln(7)] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{\ln(x+1)-\frac{x+1}{x+1}}{[\ln(x+1)]^2}.\ln(7)]$

$f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{\ln(x+1)-1}{\ln^2(x+1)}.\ln(7)] \\ \\ f'(x)=7^{\frac{x+1}{\ln(x+1)}}.[\frac{\ln(7)\ln(x+1)-1}{\ln^2(x+1)}] \\ \\ \left[\begin{array}{ccc}f'(x)=\frac{\ln(7)7^{\frac{x+1}{\ln(x+1)}}\ln(x+1)-1}{\ln^2(x+1)}\end{array}\right]$

Mhary11 Obrigada

Mhary11 podias esclarecer algo? resolvestes de várias formas o mesmo exercício ou é um só

Mhary11 Podes ajudar me a resolver outro exercício
