Question 14: Perform division A:B with \(A=-\frac{10}{3} x^{6} y^{5} z^{2} ; \quad B=\frac{1}{ 9} x^{2} yz \)
\(\mathrm{~A}: \mathrm{B}=\left(-\frac{10}{3} \mathrm{x}^{6} \mathrm{y}^{5} \mathrm{z} ^{2}\right):\left(\frac{1}{9} \mathrm{x}^{2} \mathrm{yz}\right)=-30 \mathrm{x}^{4} \mathrm {y}^{4} \mathrm{z} \)
