64.35-23.6-12.16怎么简算？

Answer 1

这道题可以简便计算，运用四则运算法则，先将后两项合并求和，23.6+12.16=35.76，再用64.35-35.76求差即可。解题思路如下：64.35-23.6-12.16=64.35-(23.6+12.16)=64.35-35.76=64.35-35.35-0.41=29-0.41=28.59 谢谢

Answer 2

lim(x->无穷) (3x^2+4x-6)/(4x^2-3x+2)

分子分母同时除x^2

=lim(x->无穷) (3+4/x-6/x^2)/(4-3/x+2/x^2)

lim(x->无穷) 4/x=lim(x->无穷)6/x^2=lim(x->无穷)3/x=lim(x->无穷)2/x^2 =0

=(3+0-0)/(4-0+0)

=3/4

Answer 3

原式=64.35-12.35+0.19-23.6
=52.19-23.6
=52.19-（22.19+1.41）
=30-1.41
=28.59

Answer 4

64.35-23.6-12.16怎么简算？
64.35-23.6-12.16
=64.35-(23.6+12.16）
=64.35-35.76
=28.59

Answer 5

用拆分法简便
64.35－23.6－12.16
=60+4.35－20－3.6－20+7.84
=28.59
