Serie 7. Utiliza el método adecuado y las fórmulas apropiadas para resolver las siguientes integrales. 1. \( \int\left(\sqrt[3]{x^{2}}+\frac{2}{\sqrt{x}}\right) d x= \)

\( \frac{2^{2 a}+2^{2 a-1}}{4^{a+1}-2^{2 a+3}} \) ifad

5. \( (61.8 \times 1.7)+9.5 \)

Using implicit differentiation, find \( \frac{d y}{d x} \) \[ -2 \cos (4 x) \sin \left(3 y^{3}\right)=6-7 x \] Provide your answer below: \[ \frac{d y}{d x}= \]
