$\displaystyle\bf\\1)\\\\\Big(\frac{1}{6}\Big)^{3} \cdot 24^{3} =\frac{1}{6^{3} } \cdot(6\cdot 4)^{3} =\frac{6^{3}\cdot 4^{3} }{6^{3} } =4^{3} =64\\\\2)\\\\(1,2)^{6} \cdot\Big(1\frac{1}{4} \Big)^{6} =\Big(\frac{6}{5}\Big )^{6} \cdot\Big(\frac{5}{4} \Big)^{6} =\Big(\frac{6\cdot 5}{5\cdot 4} \Big)^{6} =\\\\\\=\Big(\frac{3}{2} \Big)^{6} =11,390625\\\\3)\\\\0,25^{6} \cdot 4^{7} =\Big(\frac{1}{4} \Big)^{6} \cdot 4^{7} =4^{-6} \cdot 4^{7} =4^{-6+7} =4$
