原式=1.28*2.37-2.8/10*10*0.237=1.28*2.37-0.28*2.37=(1.28-0.28)*2.37=2.37
(1)18.32-5.47-4.32=18.32-4.32-5.47=14-5.47=8.53(2)13.4-(3.4+5.2)=13.4-3.4-5.2=10-5.2=4.8(3)17.29-5.2
1.63+2.37÷0.3=1.63+7.9=9.53
奥数?打字不易,如满意,望采纳.
23.23
43.2*1000/3600=12m/s
4.32×101-4.32=4.32x(101-1)=4.32x100=432手机提问的朋友在客户端右上角评价点【满意】即可.
43.2km=43200mh=3600s43.2km/h=43200m/3600s=12m/s
15.64减(5.64减2.7)=15.64-5.64+2.7=10+2.7=12.74.32乘1.8加2.2乘4.32=4.32×(1.8+2.2)=4.32×4=17.28168.1÷(4.3乘2
5.68×4+4.32÷0.25=5.68×4+4.32×4=(5.68+4.32)×4=10×4=40
(1)2.37×6.3+2.37×3.7=2.37×(6.3+3.7)=2.37×10=23.7;(2)2.5×1.25×0.32=2.5×1.25×0.8×0.4=(2.5×0.4)×(1.25×0
题目应该是:2.37*6.3+2.37*3.7?2.37*6.3+2.37*3.7=2.37*(6.3+3.7)=2.37*10=23.7
W=Pt100Km消耗的能量是3.6X106J需要的时间是100km/18km/hX3600=20000sP=180W(2)电池可以提供的P=36VX12A=432W可提供t=432/180=2.4h
原式=2.37x6.3+2.37x3.7=2.37x(6.3+3.7)=2.37x10=23.7
1.125*3+125*5+25*3+252.9999*3+101*11*(101-92)3.(23/4-3/4)*(3*6+2)4.3/7×49/9-4/35.8/9×15/36+1/276.12×
99x2.37+3.37=99x2.37+2.37+1=2.37x(99+1)+1=237+1=238
2.37×2.7=2.37×(3-0.3)=2.37×3-2.37×0.3=7.11-0.711=6.399
4.32×(7.9加12.1)再答:采纳我吧再答:4.32×20再答:=86.4再答:采纳我吧
原式=(99+1)×2.37=100×2.37=237
