3.8*4.4+0.44*62简便运算
3.8*4.4+0.44*62简便运算
3.8*4.4+0.44*62简便运算
3.8x4.4+0.44x62
=3.8x4.4+4.4x6.2
=(3.8+6.2)x4.4
=10x4.4
=44
3.8*4.4+0.44*62
=3.8*4.4+4.4*6.2
=4.4*（3.8+6.2）
=4.4*10
=44
3.8*4.4+0.44*62
=4.4*(3.8+6.2)
=4.4*10
=44
原式=38*0.44+62*0.44
=（38+62）*0.44
=100*0.44=44
38*0.44+62*0.44
=（38+62）*0.44
=100*0.44
=44
