Answer 1

Resposta:

Explicação passo-a-passo:

$\displaystyle \frac{18a^{2}b^{4}c^{5}}{34xb^{7}c^{2}}=\\\\\\\frac{18\div2}{34\div2}.\frac{a^{2}}{x}.\frac{b^{4}}{b^{7}}.\frac{c^{5}}{c^{2}}=\\\\\\\frac{9}{17}.\frac{a^{2}}{x}.b^{(4-7)}.c^{(5-2)}=\\\\\\\frac{9}{17}.\frac{a^{2}}{x}.b^{(-3)}.c^{(3)}=\\\\\\\frac{9}{17}.\frac{a^{2}}{x}.\frac{1}{b^{3}}.c^{3}=\\\\\\\frac{9a^{2}c^{3}}{17xb^{3}}$
