$( \frac{1}{6} x^{-4} y^{3} ) ^{-1}=( \frac{1}{6} ) ^{-1} *( x^{-4} ) ^{-1} *( y^{3}) ^{-1} = \frac{6 x^{4} }{y ^{3} }$

$( \frac{3 a^{-4} }{2 b^{-3} } ) ^{-2} *10 a^{7} b^{3} =( \frac{2 a^{4} }{3 b^{3} } ) ^{2}*10 a^{7} b^{3} = [tex] \frac{40 a^{15} }{9b ^{3} }$

А). (1/6x^-4 • y^3)^-1 = 6x^4 • 1/y^3;

б). (3а^-4/2b^-3)^-2 • 10a^7 • b^3 = (9a^8/4b^6) • 10a^7 • b^3 = 45a^15/2b^3.
