3)

$\frac{(x^{2})^{3} * (x^{3})^{4} * (x^{4})^{5}}{((x^{2})^{3})^{5}} \\\\ \frac{(x^{6})* (x^{12}) * (x^{20})}{(x^{30})} \\\\ x^{6 + 12 + 20 - 30} \\\\ x^{8}$

Respuesta: Opción c

4)

$E = 16^{-4^{-2^{-1} } } \\\\ E = 16^{-4^{-\frac{1}{2} } } \\\\ E = 16^{-(\frac{1}{4}) ^{\frac{1}{2} } } \\\\ E = 16^{-\sqrt{\frac{1}{4} } } } \\\\ E = 16^{-\frac{1}{2} } } \\\\ E = (\frac{1}{16})^{\frac{1}{2} } } \\\\ E = \sqrt{\frac{1}{16} } \\\\ E = \frac{1}{4}$

Respuesta: Opción b
