Step-by-step Solution
Vamos a resolver las derivadas de cada una de las funciones dadas.
### 1) \( f(x)=\left(\frac{3}{5} x^{-1 / 4}+\frac{2 x}{\sqrt{x}}\right)^{2} \)
Primero simplificamos la función:
\[
f(x) = \left(\frac{3}{5} x^{-1/4} + 2 x^{1/2}\right)^{2}
\]
Usamos la regla de la cadena y la regla del producto para derivar:
\[
f'(x) = 2\left(\frac{3}{5} x^{-1/4} + 2 x^{1/2}\right) \cdot \left(-\frac{3}{20} x^{-5/4} + x^{-1/2}\right)
\]
### 2) \( f(x)=-\frac{1}{5}\left(5 x^{-4}+2 x\right) \)
Simplificamos:
\[
f(x) = -x^{-4} - \frac{2}{5} x
\]
Derivamos:
\[
f'(x) = 4 x^{-5} - \frac{2}{5}
\]
### 3) \( f(x)=\sqrt{100} \)
Dado que \( \sqrt{100} = 10 \), la función es constante:
\[
f'(x) = 0
\]
### 4) \( f(x)=\left(-\frac{1}{6} x^{3}-3 x^{-2}\right)\left(\sqrt{x}+3 x^{9}\right) \)
Usamos la regla del producto:
\[
u = -\frac{1}{6} x^{3} - 3 x^{-2}, \quad v = \sqrt{x} + 3 x^{9}
\]
Derivamos \( u \) y \( v \):
\[
u' = -\frac{1}{2} x^{2} + 6 x^{-3}
\]
\[
v' = \frac{1}{2} x^{-1/2} + 27 x^{8}
\]
Aplicamos la regla del producto:
\[
f'(x) = u'v + uv'
\]
### 5) \( f(x)=2 x^{-1 / 2} \)
Derivamos:
\[
f'(x) = -x^{-3/2}
\]
### Resumen de las derivadas:
1) \( f'(x) = 2\left(\frac{3}{5} x^{-1/4} + 2 x^{1/2}\right) \cdot \left(-\frac{3}{20} x^{-5/4} + x^{-1/2}\right) \)
2) \( f'(x) = 4 x^{-5} - \frac{2}{5} \)
3) \( f'(x) = 0 \)
4) \( f'(x) = u'v + uv' \) (donde \( u' \) y \( v' \) se calcularon anteriormente)
5) \( f'(x) = -x^{-3/2} \)
Quick Answer
1) \( f'(x) = 2\left(\frac{3}{5} x^{-1/4} + 2 x^{1/2}\right) \cdot \left(-\frac{3}{20} x^{-5/4} + x^{-1/2}\right) \)
2) \( f'(x) = 4 x^{-5} - \frac{2}{5} \)
3) \( f'(x) = 0 \)
4) \( f'(x) = u'v + uv' \) (where \( u' \) and \( v' \) were calculated previously)
5) \( f'(x) = -x^{-3/2} \)
