化简：(2x-y)ˆ7•[3(2x-y)]ˆ2/[2/3(2x-y)ˆ3]ˆ3化简：(2x-y)ˆ7•[3(2x-y)]
化简：(2x-y)ˆ7 • [3(2x-y)]ˆ2 / [2/3(2x-y)ˆ3]ˆ3
化简：(2x-y)ˆ7 • [3(2x-y)]ˆ2 / [2/3(2x-y)ˆ3]ˆ3
化简：(2x-y)ˆ7 • [3(2x-y)]ˆ2 / [2/3(2x-y)ˆ3]ˆ3
(2x-y)^7*[3(2x-y)]^2/[2/3(2x-y)^3]^3
=(2x-y)^7*9(2x-y)^2/[8/27(2x-y)^9]
=9(2x-y)^9/[8/27(2x-y)^9]
=9/(8/27)
=9×27/8
=243/8
好多字母啊啊 看着都不想写
