题型:数学计算
解:
2.53*2.5+17*2.5+2.82*1.5+3*3.57+4*3.25+3.81+3.73*3+3*1.83
=6.325+17*2.5+2.82*1.5+3*3.57+4*3.25+3.81+3.73*3+3*1.83
=6.325+42.5+2.82*1.5+3*3.57+4*3.25+3.81+3.73*3+3*1.83
=6.325+42.5+4.23+3*3.57+4*3.25+3.81+3.73*3+3*1.83
=6.325+42.5+4.23+10.71+4*3.25+3.81+3.73*3+3*1.83
=6.325+42.5+4.23+10.71+13+3.81+3.73*3+3*1.83
=6.325+42.5+4.23+10.71+13+3.81+11.19+3*1.83
=6.325+42.5+4.23+10.71+13+3.81+11.19+5.49
=48.825+4.23+10.71+13+3.81+11.19+5.49
=53.055+10.71+13+3.81+11.19+5.49
=63.765+13+3.81+11.19+5.49
=76.765+3.81+11.19+5.49
=80.575+11.19+5.49
=91.765+5.49
=97.255 答案:2.53*2.5+17*2.5+2.82*1.5+3*3.57+4*3.25+3.81+3.73*3+3*1.83=97.255你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
