3.6x1.9+0.36x81=3.6x(1.9+多少)

解:原式=3.6x1.9+3.6x8.1 =3.6x(1.9+8.1) =3.6x10 =36 【很高兴你解决以上问题,希望对你的学习有所帮助!】≤、≥ ∠

原式=3.6x1.9+3.6x8.1=3.6x(1.9+8.1)=3.6x10=36【很高兴你解决以上问题,希望对你的学习有所帮助!】≤、≥ ∠

3.6x1.9+0.36x81可以写为3.6x1.9+3.6x8.1=(1.9+8.1)*3.6=10*3.6=36

3.6x1.9+36x0.81 =3.6x1.9+3.6x8.1= 3.6x(1.9+8.1)=3.6x10=36

3.6x1.9+3.6x8.1=3.6*(1.9+8.1)=3.6*10=36

3.6x1.9十36x0.81=3.6*【1.9*8.1】=3.6*10=36 满意采纳

你好,3.6*(1.9+8.1)=36

3.6*0.81+0.36*1.9=3.6*0.81+3.6*0.19=3.6*(0.81+0.19)=3.6*1=3.6祝学习进步

3.6x0.8+1.6x0.36=0.36*8+1.6*0.36=0.36*(8+1.6)=0.36*9.6=0.36*(10-0.4)=0.36*10-0.36*0.4=3.6-0.144=3.456

3.6x0.8+0.36x1.9=3.6x0.8+3.6x0.19=3.6x(0.8+0.19)=3.6x(1-0.01)=3.6-3.6x0.01=3.6-0.036=3.564
