(8.6+8.6+8.6+8.6×5)×12.5简便运算
(8.6+8.6+8.6+8.6×5)×12.5简便运算

(8.6+8.6+8.6+8.6×5)×12.5简便运算
原式=[8.6×(1+1+1+5)]×12.5
=8.6×8×12.5
=8.6×(8×12.5)
=8.6×100
=860

(8.6+8.6+8.6+8.6×5)×12.5
=8.6(1+1+1+5)×12.5
=8.6×8×12.5
=8.6×100
=860

原式=[8.6×(1+1+1+5)]×12.5
=8.6×8×12.5
=8.6×(8×12.5)
=8.6×100
=860

(8.6+8.6+8.6+8.6×5)×12.5
=(8.6X8)x12.5
=8.6X8X12.5
=8.6X(8X12.5)
=8.6X100
=860

(8.6+8.6+8.6+8.6×5)×12.5
=8.6x8x12.5
=8.6x100
=860

8*8.6*12.5=100*8.6=860

ms现在小学生做作业都是百度的。。。
