Answer 1

5.7×65+57×3.7-11.4
=5.7×65+5.7×10×3.7-5.7×2
=5.7×(65+10×3.7-2)
=5.7×100
=570

Answer 2

5.7×65+57×3.7-11.4=5.7×65+5.7×37-5.7×2=5.7×(65+37-2)=5.7×100=570

Answer 3

5.7×65+57×3.7-11.4等于多少简便计算？
5.7×65+57×3.7-11.4
=5.7*(65+37)-11.4
=5.7*102-11.4
=581.4-11.4
=570

Answer 4

5.7*65+57*3.7-11.4
=57*6.5+57*3.7-11.4
=57*(6.5+3.5+0.2)-11.4
=57*10+57*0.2-11.4
=570+11.4-11.4
=570
求采纳，谢谢！

Answer 5

5.7×65+57×3.7-11.4
=5.7×65+5.7×37-5.7×2
=5.7×（65+37-2）
=5.7×100
=570

Answer 6

5.7x65+57x3.7-11.4
＝57x6.5+57x3.7-11.4
＝57x(6.5+3.7)-11.4
＝57x10.2-11.4
＝581.4-11.4
＝570
