(3a^-2b^-4)²·(2a³b³)²/(3^-1a²b³）^-3计算
(3a^-2b^-4)²·(2a³b³)²/(3^-1a²b³）^-3计算

(3a^-2b^-4)²·(2a³b³)²/(3^-1a²b³）^-3计算
(3a^-2b^-4)²·(2a³b³)²/(3^-1a²b³）^-3
=9a^(-4)·b^(-8)·4a^6·b^6/(27a^-6·b^-9)
=(4/3)·a²b^(-2)·a^6·b^9
=(4/3)·a^8·b^7

解
(3a^-2b^-4)²·(2a³b³)²/(3^-1a²b³）^-3
=[9a^(-4)*b^(-8)][4a^6*b^6]*[3^-3a^6b^9]
=(36*1/27)a^(-4+6+6)b^(-8+6+9)
=4/3a^8b^7
