Упростите выражение:
1) $2a^{3} * (-5a^{4}b^{5})^{2}$;
2) $(-x^{6}y)^{3} * 11x^{4}y^{5}$;
3) $(-0,6a^{3}b^{5}c^{6})^{2} * 3a^{2}c^{8}$;
4) $-1\frac{3}{11}m^{4}n^{9} * (-\frac{1}{7}mn^{3})^{2}$;
5) $1\frac{7}{9}x^{7}y^{2} * (\frac{3}{4}x^{2}y^{9})^{4}$;
6) $-(-2c^{2}d^{5})^{7} * (-\frac{1}{2}c^{4}d^{5})^{4}$.
$2a^{3} * (-5a^{4}b^{5})^{2} = 2a^{3} * 25a^{8}b^{10} = 50a^{11}b^{10}$
$(-x^{6}y)^{3} * 11x^{4}y^{5} = (-1)^{3}x^{18}y^{3} * 11x^{4}y^{5} = -11x^{22}y^{8}$
$(-0,6a^{3}b^{5}c^{6})^{2} * 3a^{2}c^{8} = 0,36a^{6}b^{10}c^{12} * 3a^{2}c^{8} = 1,08a^{8}b^{10}c^{20}$
$-1\frac{3}{11}m^{4}n^{9} * (-\frac{1}{7}mn^{3})^{2} = -\frac{14}{11}m^{4}n^{9} * \frac{1}{49}m^{2}n^{6} = (-\frac{14}{11} * \frac{1}{49})m^{6}n^{15} = (-\frac{2}{11} * \frac{1}{7})m^{6}n^{15} = -\frac{2}{77}m^{6}n^{15}$
$1\frac{7}{9}x^{7}y^{2} * (\frac{3}{4}x^{2}y^{9})^{4} = \frac{16}{9}x^{7}y^{2} * \frac{81}{256}x^{8}y^{36} = (\frac{16}{9} * \frac{81}{256})x^{15}y^{38} = (\frac{1}{1} * \frac{9}{16})x^{15}y^{38} = \frac{9}{16}x^{15}y^{38}$
$-(-2c^{2}d^{5})^{7} * (-\frac{1}{2}c^{4}d^{5})^{4} = -(-128c^{14}d^{35}) * \frac{1}{16}c^{16}d^{20} = 128c^{14}d^{35} * \frac{1}{16}c^{16}d^{20} = 8c^{30}d^{55}$
