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

这道计算题怎么简算?9.81×0.1+0.5×98.1+0.049×981
求帮忙解决2道简算题.9.81×0.1+0.5×98.1+0.049×981999×222+333×334
0.1X+0.5(30-X)=9.8
(0.2+0.4+0.6+...+9.8+10)-(+0.1+0.3+0.5+...+9.7+9.9)
12+[0.4*0.75+(0.5+?)*3]/0.3=98 等于几 9.81*0.1+0.5*98.1+0.049*981= 6789.6789/6.789=每题简算
问几道算式,要用简便方法,急用!算式——75*76分之39.81*0.1+0.5*98.1+0.049*98156.8*10.139.5*3.6+843*0.96895.6785/6.785*67.853333*6666
表面抗体9.9（参考值0.0--10）,E抗原0.1（0.0--0.5）,其他全是0.急
(0.2+0.4+0.6+…+9.8+10)-(0.1+0.3+0.5+…+9.7+9.9)简便计算急
得0.1X+0.5（30-X）=9.8 解得X=13 求过程
