（5÷3☆3÷4）☆4÷3
=(5/3☆3/2）☆4/3
=[3*(5/3)-2*(3/2)]☆4/3
=2☆4/3
=3*2-2*4/3
=6-8/3
=10/3（5÷3☆3÷4）☆4÷3=(5/3☆3/2……不是3/4吗，怎么会是3/2）☆4/3…………=[3*(5/3)-2*(3/2)]☆4/3=2☆4/3=3*2-2*4/3=6-8/3=10/3我脑子短路了，让百度给闹的。昨天的采纳很多给删除了我重做（5÷3☆3÷4）☆4÷3=(5/3☆3/4）☆4/3=[3*(5/3)-2*(3/4)]☆4/3=(7/2)☆4/3=3*(7/2) - 2*4/3=21/2-8/3=47/6=10/3
