介电常数,又称为介质常数或电容率,是衡量物质在电场中存储电荷能力的物理量。它反映了物质对电场的响应程度,决定了电介质中电场的分布和电容器的性能。介电常数越大,物质在电场中储存电荷的能力越强,电场在物质中的衰减也越快。通过测量物质的介电常数,...

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!!!
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!!!

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

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
=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
