Question

efetue as multiplicação  

3x²y/5a² × 10a/15xy

14p²q/15mn² × 45m²n²/7pq × nm/9p

Answer 1

$\boxed{\frac{3x^2y}{5a^2}*\frac{10a}{15xy}=\frac{30ax^2y}{75a^2xy}=\frac{2x}{5a}}\\ \\ \boxed{\frac{14p^2q}{15mn^2}*\frac{45m^2n^2}{7pq}*\frac{nm}{9p}=\frac{630m^3n^3p^2q}{945mn^2p^2q}=\frac{2m^2n}{3}}$
