4 25 65 25 28

你好:4*(25*65+25*28)=4*25*(65+28)=100*93=9300

原式=4x25x(65+28)=4x25x93=100x93=9300 供参考.

把它换算一下,原式=4*25*(65+28)=100*93=9300

4*25*65+25*8=(4*25)*65+4*2*25=100*65*2*100=100(65+2)=6700

原式=4*25*65+4*25*28=4*25*(65+28)=100*93=9300

=4*25*(65+28) =4*25*93 =100*93 =9300

4*(25*65+25*28)=4*25*(65+28)=100*93=9300

4x(25x65+25x28)的简便运算结果等于9300.解:方法一4x(25x65+25x28)=4x25x(65+28)=(4x25)x93=100x93=93000 方法二4x(25x65+25x28)=4x25x65+4x25x28=100x65+100x28=6500+2800=9300 扩展资料:1、乘法结合律 (axb)xc=ax(

解: 4x(25x65+25x28) =(4x25)x65+(4x25)x28 =100x65+100x28 =6500+2800 =9300 亲,请您点击【采纳答案】,您的采纳是我答题的动力,如果不明白,请追问,谢谢.
