Question

5·7ⅹ3·26+326ⅹ0·7用脱式怎样简便计算？

Answer 1

此题可以用乘法分配律进行简便计算
5.7x3.26+326x0.7
=5.7x3.26+3.26x70
=（5.7+70）x3.26
=75.7x3.26
=246.782

Answer 2

5·7ⅹ3·26+326ⅹ0·7用脱式怎样简便计算？
解：5·7ⅹ3·26+326ⅹ0·7
=5.7x3.26+3.26x100x0.7
=3.26x（5.7+70）
=3.26x75.7
=246.782

Answer 3

5.7*3.26+326*0.7=5.7*3.26+3.26*70=3.26*（5.7+70）=3.26*75.7=246.782

Answer 4

答：5·7ⅹ3·26+326ⅹ0·7 简便计算式
=5.7ⅹ3.26+3.26ⅹ100ⅹ0.7
=（5.7+100ⅹ0.7）ⅹ3.26
=5ⅹ3.26+0.7ⅹ3.26+70ⅹ3.26
=16.3+2.282+228.2
=246.782

Answer 5

5.7*3.26+326*0.7
=5.7*3.26+3.26*100*0.7
=3.26*（5.7+70）
=3.26*75.7
=246.782
这是最简便的方法
