Bài 2: Làm tính chia:
a) \((x^{3}y^{3}-\frac{1}{2}x^{2}y^{-x^{3}y^{2}})\cdot\frac{1}{3}x^{-2}y^{-2};\)
b) \((15x^{2}y^{4}+7x^{3}y^{5}-6x^{4}y^{6})\cdot\left(-\frac{1}{2}x^{-2}y^{-4}\right)\)
c) \(\left(-24x^{4}y^{3}+\frac{1}{5}x^{6}y^{2}-\frac{2}{7}x^{8}y\right)\cdot\left(\frac{1}{3}x^{4}y\right)\)
d) \(\left(\frac{2}{3}x^{8}y^{7}-\frac{3}{4}x^{7}y^{6}+ \frac{4}{5}x^{6}y^{5}\right)\cdot\left(-\frac{5}{6}x^{-5}y^{4}\right)\)
