6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算啊,6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算啊,6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算

6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算啊,
6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算啊,

6.8*0.41+0.59*3.4*2能简算么,如果能,怎么简算啊,
6.8 × 0.41 + 0.59 × 3.4 × 2
= 6.8 × 0.41 + 0.59 × 6.8
= 6.8 × (0.41 + 0.59)
= 6.8× 1
= 6.8

先算出3.4*2=6.8
提出6.8得:6.8(0.41+0.59)=6.8

6.8*0.41+0.59*3.4*2 =6.8*0.41+0.59*6.8
=6.8 * ( 0.41+0.59 )
=6.8 * 1 = 6.8
