Question

Решите производную.....

Answer 1

Произведение функций =  u(x)=√x,  v(x) = 1/(4+x).

g(x) = 1/(2*√x  * 1/(4+x)) - √x/(4+x)² - ОТВЕТ

Answer 2

$f(x)=frac{sqrt{x}}{4+x}\\f'(x)=frac{frac{1}{2sqrt{x}}cdot (4+x)-sqrt{x}cdot 1}{(4+x)^2}=frac{4+x-2x}{2sqrt{x}cdot (4+x)^2}=frac{4-x}{2sqrt{x}cdot (4+x)^2}$
