Question

Preciso de ajuda. Por favor.

Answer 1

a)

$\frac{2^5.5^{13}}{2^9.5^6}=\frac{2^5.5^6.5^{7}}{2^5.2^4.5^6}=\\\\ eliminando \ os \ iguais, fica:\\\\ =\frac{5^{7}}{2^4}$

b)

$\frac{(2.3)^7.(3.5)^4}{3^9}=\frac{2^7.3^7.3^4.5^4}{3^9}=\\\\ =\frac{2^7.3^7.3^2.3^2.5^4}{3^7.3^2}=\\\\ eliminando \ os \ iguais, \ fica:\\\\ =\frac{2^7.3^2.5^4}{1}=2^7.3^2.5^4$
