问题描述:
计算
(-1)^100×5+(-2)^4÷4
=1×5+16÷4
=5+4
=9
(-3)^3-3×(1/3)^4
=(-27)-3×1/81
=(-27)-1/27
=-27又1/27
7/6×(1/6-1/3)×3/14÷3/5
=7/6×(-1/6)×3/14×5/3
=(-1/36)×3/14×5/3
=-5/504
-2^3÷4/9×(-2/3)^2
=(-8)×9/4×4/9
=-8
4+(-2)^3×5-(-0.28)÷4
=4+(-8)×5-(-0.28)÷4
=4+(-40)-(-0.07)
=4+(-40)+0.07
=-35.93
大家说我做的对么
任守榘回答:
(-1)^100×5+(-2)^4÷4
=1×5+16÷4
=5+4
=9
对
(-3)^3-3×(1/3)^4
=(-27)-3×1/81
=(-27)-1/27
=-27又1/27
对
7/6×(1/6-1/3)×3/14÷3/5
=7/6×(-1/6)×3/14×5/3
=(-1/36)×3/14×5/3=(-7/36)×3/14×5/3
=-5/504=-5/72
-2^3÷4/9×(-2/3)^2
=(-8)×9/4×4/9
=-8
对
4+(-2)^3×5-(-0.28)÷4
=4+(-8)×5-(-0.28)÷4
=4+(-40)-(-0.07)
=4+(-40)+0.07
=-35.93
对
你做的还不错,就出了一点小问题,继续努力!
