200000m= km,500000cm= m,0.0035mm= m,0.005m= km,0.007μm= m,0.00056m= nm 用科学计数法计算!
200000m= km,500000cm= m,0.0035mm= m,0.005m= km,0.007μm= m,0.00056m= nm 用科学计数法计算!
200000m= km,500000cm= m,0.0035mm= m,0.005m= km,0.007μm= m,0.00056m= nm 用科学计数法计算!
200000m=2×10^2 km,500000cm= 5×10^3m,0.0035mm=3.5×10^(-6) m,
0.005m= 5×10^(-6)km,0.007μm=7×10^(-9) m,0.00056m= 5.6×10^5nm
6370km m=?cm

200000m= km,500000cm= m,0.0035mm= m,0.005m= km,0.007μm= m,0.00056m= nm 用科学计数法计算!
860cm=( )cm 7000m=( )km
单位换算2.5km =多少m=多少cm
2.5km =多少m=多少cm
6370km=?m=?cm 科学计数法
