0.25×0.4×14.5=0.1×14.5=1.45

3.25×4×1.1×（13+0.7）=13×1.1×13+13×1.1×0.7=195.91

12.8+（2+0.04）×9.5=12.8+2×9.5+0.04×9.5=32.18

（0.25-0.02）×4+0.75=0.25×4-0.02×4+0.75=1.67

Answer 2

如图

Answer 3

1, =0.25x0.4x14.5=0.1x14.5=1.45
2, =12.8+2.04(10-0.5)=12.8+20.4-1.02=32.18
5, = (3+0.25)(4+0.4)x13.7=(12+1+1.2+0.1)13.7=14.3x13.7=(14+0.3)(14-0.3)=14^2-0.3^2=196-0.09=195.91
6, =(0.25-0.02)x4+0.75=1-0.08+0.75=1.67

Answer 4

=1.45
=195.91
=32.18
=1.67
