Question

4.6×4.6+4.65×4的简便计算？

Answer 1

4.6ⅹ4.6+4.65x4
=4.6ⅹ4.6+4.6ⅹ4+0.05x4
=4.6ⅹ(4.6+4)+0.2
=4.6x8.6+0.2
=39.56+0.2
=39.76

Answer 2

4.6ⅹ4.6+4.65x4
=4.6ⅹ4.6+4.6ⅹ4+0.05x4
=4.6ⅹ(4.6+4)+0.2
=4.6x8.6+0.2
=39.56+0.2
=39.76

Answer 3

4.6×4.6+4.65×4=4.6×5－4.6×0.4+4.6×4+0.05×4=23－0.46×4+18.4+0.05×4=41.4－1.84+0.2=41.6－1.84=39.76

Answer 4

4.6x4.6+4.65x4
=4.6x4.6+（4.6+0.05）x4
=4.6x4.6+4.6x4+0.05x4
=4.6x（4.6+4）+0.2
=4.6x8.6+0.2
=（5-0.4）x8.6+0.2
=8.6x5-0.4x8.6+0.2
=43-3.44+0.2
=39.76

Answer 5

4.6x4.6+4.65x4
=4.6×4.6十(4.6+0.05)×4
=4.6X4.6+4.6×4+0.05X4
=4.6×(4.6+4)+0.2
=4.6×8+4.6×0.6+0.2
=37+2.76
=39.76
