1.53×10的五次方km= ( )=( )mm4.76×10的四次方nm=( )=( )m

问题描述:

1.53×10的五次方km= ( )=( )mm
4.76×10的四次方nm=( )=( )m

1.53x10^5 km = 1.53x 10^8 m =1.53x 10^11mm
4.76x10^4nm = 4.76x 10^-2mm=4.76x10^-5 m

1.53×10^8,1.53×10^11
4.76×10^-2,4.76×10^-5

1.53x10^5 km = 1.53x 10^8 m =1.53x 10^11mm
4.76x10^4nm = 4.76x 10^-2mm=4.76x10^-5 m
