Question

efetue as seguintes divisões:​

Answer 1

A)

$\frac{( \frac{2}{7} {a}^{4} {x}^{3} )}{( \frac{4}{7} a {x}^{2}) } = \frac{2}{7} \times \frac{7}{4} = \frac{14}{28} {a}^{3} x = \frac{2}{4} {a}^{3} x$

Simplifica o 14/28 com 7!!

B)

$\frac{( - \frac{1}{2} {a}^{2} {n}^{7}) }{( \frac{1}{8} a {n}^{6} )} = - \frac{1}{2} \times \frac{8}{1} = \frac{ - 8}{ - 2} = 4an$
