$\displaystyle\bf\\1)\\\\\frac{(a\cdot b)^{3} }{b^{2} } =\frac{a^{3} \cdot b^{3} }{b^{2} } =\frac{a^{3} \cdot b\cdot b^{2} }{b^{2} } =a^{3} b\\\\2)\\\\\Big(\frac{x}{y} \Big)^{5} \cdot y^{7} =\frac{x^{5} \cdot y^{7} }{y^{5} } =\frac{x^{5}\cdot y^{5} \cdot y^{2} }{y^{5} } =x^{5} y^{2}\\\\3)\\\\\frac{(d\cdot t)^{9} }{d^{7} } =\frac{d^{9}\cdot t^{9} }{d^{7} } =\frac{d^{7} \cdot d^{2} \cdot t^{9} }{d^{7} } =d^{2} t^{9}$

$\displaystyle\bf\\4)\\\\\frac{(x\cdot y)^{6} }{x^{5} } =\frac{x^{6}\cdot y^{6} }{x^{5} } =\frac{x^{5} \cdot x\cdot y^{6} }{x^{5} } =x y^{6} \\\\5)\\\\\frac{(a\cdot c)^{10} }{c^{8} } =\frac{a^{10}\cdot c^{10} }{c^{8} } =\frac{a^{10} \cdot c^{8} \cdot c^{2} }{c^{8} } =a^{10} c^{2} \\\\6)\\\\m^{12}\cdot \Big(\frac{n}{m} \Big)^{10} =\frac{m^{12}\cdot n^{10} }{m^{10} } =\frac{m^{10} \cdot m^{2} \cdot n^{10} }{m^{10} } =m^{2} n^{10}$
