Question

Упростите выражение:
$\ \textless \ br /\ \textgreater \ а)\ \textless \ br /\ \textgreater \ \frac{x \times x ^{5} \times x ^{7} }{x ^{4} } \ \textless \ br /\ \textgreater \ б)\ \textless \ br /\ \textgreater \ \frac{5c ^{5} \times c}{c ^{4} }$

Answer 1

а)

$\frac{x \times x ^{5} \times x ^{7} }{x ^{4} }= \frac{x^{13}}{x^4}=x^9$

б)

$\frac{5c ^{5} \times c}{c ^{4} } = \frac{5c^6}{c^4}=5c^2$
