Question

4.6×4.6+4.65×4的简便计算？

Answer 1

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 2

4.6×4.6+4.65×4=39.76

Answer 3

这是小学五年级数学简便运算内容，一般都是用乘法交换律结合律和分配率解决，具体解答过程如下:
4.6×4.6+4.65×4
=4.6×4.6+(4.6+0.05)×4
=4.6×4.6+4.6×4+0.05×4
=4.6×(4.6+4)+0.2
=4.6×8.6+0.2
=39.56+0.2
=39.76
希望我的解答对你有所帮助！！！

Answer 4

4.6×4.6+4.65×4的简便计算
原式可变为 4.6×4.6+(4.6+0.05）×4
= 4.6×4.6+4.6×4+0.05×4
=4.6×(4.6+4)+0.2
=4.6×8+4.6×0.6+0.2
=36.8+2.76+0.2
=37+2.76
=39.76

Answer 5

4.6＊4.6+4.65＊4
=4.6＊4.6+（4.6+0.05）＊4
=4.6＊4.6+4.6＊4+0.05＊4
=4.6＊（4.6+4）+0.2
=4.6＊8.6+0.2
=8.6＊（5-0.4）+0.2
=8.6＊5-8.6＊0.4+0.2
=43-3.44+0.2
=43-3.24
=43-（4-0.76）
=43-4+0.76
=39+0.76
=39.76
