Question

3.74×3.6+0.374×4.4等于简便运算是多少？

Answer 1

3.74x3.6+0.374x 4.4
=3.74X3.6+3.74ⅹ0.44
=3.74ⅹ(3.6+0.44)
=3.74X4.04
=3.74X(4+0.04)
=3.74X4+3.74X0.04
=15.1096

Answer 2

原式=178.024

Answer 3

用乘法分配律
3.74×3.6+0.374×4.4
=3.74×3.6+3.74×0.44
=3.74（3.6+0.44）
=3.74×4.04
=3.74（4+0.04）
=14.96+0.1496
=15.1096

Answer 4

3.74×3.6+0.374×4.4
=3.74×3.6+3.74×0.44
=3.74×（3.6+0.44）
=3.74×4.04
=3.74×（4+0.04）
=14.96+0.1496
=15.1096

Answer 5

3.74*3.6+0.374*4.4
=0.374*10*3.6+0.374*4.4
=0.374*（36+4.4）
=0.374*40.4
=15.1096
这是最简便的方法
