9.8*0.1+0.5*98.1+0.049*981怎样计算简便
9.8*0.1+0.5*98.1+0.049*981怎样计算简便

9.8*0.1+0.5*98.1+0.049*981怎样计算简便
9.81*0.1+0.5*98.1+0.049*981
=9.81*0.1+5*9.81+4.9*9.81
=9.81*(0.1+5+4.9)
=9.81*10
=98.1

9.8*0.1+0.5*98.1+0.049*981
=9.8*0.1+0.5*98.1+0.49*98.1
=9.8*0.1+0.99*98.1
=0.98+98.1-0.981
=97.09

9.8*0.1+0.5*98.1+0.049*981=98×0.01+0.5×（98+0.1）+0.049×（980+1)=98×0.01+0.5×98+0.05+0.049×980+0.049=98×(0.01+0.5+0.49)+(0.05+0.049)=98+0.99=98.99
