已知a=0.0...012 199个0,b=0.0...025 100个0,c=0.0...08 100个0,求a/(b*c)

已知a=0.0...012 199个0,b=0.0...025 100个0,c=0.0...08 100个0,求a/(b*c)
已知a=0.0...012 199个0,b=0.0...025 100个0,c=0.0...08 100个0,求a/(b*c)

已知a=0.0...012 199个0,b=0.0...025 100个0,c=0.0...08 100个0,求a/(b*c)
a/(b*c)
=0.0...012 /(0.0...025*0.0...08)
=1.2*10^(-100)/[2.5*10^(-100)*8*10^(-100)]
=1.2/[2.5*8*10^(-100)]
=1.2/[20*10^(-100)]
=1.2/[2*10^(-99)]
=(1.2/2)*10^99
=0.6*10^99
=6*10^98
a/(b*c)=6后面有98个0

6*10的100次方
