Question

5.29×3.6＋0.529×64简便运算？

Answer 1

简便运算是直接提取公约数 5.29得

原式=5.29x(3.6+6.4)
=5.29x10
=52.9

Answer 2

5.29×3.6＋0.529×64

=5.29×3.6＋5.29×6.4     ..............根据积不变的性质改写

=5.29×（3.6+6.4）     ............乘法的分配律

=5.29×10

=52.9

Answer 3

5.29×3.6＋0.529×64
=5.29×3.6+5.29×6.4
=5.29×（3.6+6.4）
=5.29×10
=52.9

Answer 4

你好，这道题简便运算是利用乘法分配律计算。原式=5.29x3.6+5.29x6.4=5.29x(3.6+6.4)=5.29x10=52.9。

Answer 5

乘法分配律
5.29×3.6+0.529×64
＝0.529×36+0.529×64
＝0.529×（36+64）
＝0.529×100
＝52.9
