答案

解:(1)(a23·(a24÷(﹣a25

                  =a6·a8÷(﹣a10

                  =a14÷(﹣a10

                  =﹣a4

(2)(x34+(x26

          =x12+x12

          =2x12

(3)(﹣2a2b34+(﹣a)8(2b43

          =16a8b12+8a8b12

          =24a8b12

(4)(0.125)2006·(﹣8)2007·(﹣1)2006

          =(2006·(﹣8)2006·(﹣8)·1

       =[×(﹣8)]2006·(﹣8)

       =(﹣1)2006·(﹣8)

       =﹣8;

(5)(p﹣q)4÷(q﹣p)3·(p﹣q)2

          =(p﹣q)4÷[﹣(p﹣q)3]·(p﹣q)2

        =﹣(p﹣q)4﹣3+2

        =﹣(p﹣q)3

        =(q﹣p)2

(6)4﹣(﹣2)﹣2﹣32÷(3.14﹣π)0

        =4﹣﹣9÷1

        =4﹣﹣9

        =﹣5
