答案
(1)原式=96×2000+2000-96×2000-96 | |
=2000-96 | |
=1904 | (2)原式=999×(999+1)×100 |
=99900000 | |
(3)原式=(1.25×8)×(0.25×4)×(0.05×2) | |
=10×1×0.1 | |
=1 | (4)原式=9.728÷(3.2×2.5) |
=9.728÷8 | |
=1.216 | |
(5)原式=9876×9876-9875×9879-9875 |
=9876-9875
=1
=38.4×33+3.3×16
=(384+16)×3.3
=1320
(7)原式=8.46×(36+×64)
=846
=33333×(1234-1234)
=0
(9)原式=(0.2-0.0001)+(2-0.001)+(20-0.01)+(200-0.1)
=(0.2+2+20+200)-(0.0001+0.001+0.01+0.1)
=222.2-0.1111
=222.0889
(10)原式=(0.01+0.04+0.09+0.16)2÷(0.001+0.008+0.027+0.64)3
=(0.3)2÷(0.1)3
=90
