计算:(1)(2x²/3y﹚²﹙3y/4x﹚³;(2)a²-4b²/a²ab·a-b/a²-ab十万火急。(2)(a²-

计算:(1)(2x²/3y﹚²﹙3y/4x﹚³;(2)a²-4b²/a²ab·a-b/a²-ab十万火急。(2)(a²-4b²/a²-ab)×(a-b/a²-ab)
计算:(1)(2x²/3y﹚²﹙3y/4x﹚³;(2)a²-4b²/a²ab·a-b/a²-ab
十万火急。(2)(a²-4b²/a²-ab)×(a-b/a²-ab)

计算:(1)(2x²/3y﹚²﹙3y/4x﹚³;(2)a²-4b²/a²ab·a-b/a²-ab十万火急。(2)(a²-4b²/a²-ab)×(a-b/a²-ab)
(1)(4X^4/3Y²)(27Y³/64X³)
=9XY/16
(2)(A+2B)(A-2B)/A(A-B)×(A-B)/A(A-B)
=A²-4B²/A³-A²B

(1)3xy/16 第二个太乱了 写开点再帮你算
