13X25＋65X25＋22x25简便计算？ 50x(2x4)x25。用除法的性质与简便运算。怎么算？
28x255\u4e002x25\u4e006x25\u7684\u7b80\u4fbf\u7b97\u6cd528x255-2x25-6x25
=28x(250+5)-(2+6)x25
=28x250+28x5-8x25
=280x25+140-8x25
=(280-8)x25+140
=272x25+140
=68x4x25+140
=68x100+140
=6800+140
=6940
50\u00d7(2\u00d74)\u00d725
=50\u00d72\u00d74\u00d725
=(50\u00d72)\u00d7(4\u00d725)
=100\u00d7100
=10000
