Question

大家帮我这些题对么
计算
(-1)^100×5+(-2)^4÷4
=1×5+16÷4
=5+4
=9
7/6×(1/6-1/3)×3/14÷3/5
=7/6×(-1/6)×3/14×5/3
=-7/36×3/14×5/3
=-5/72
(-10)^3+〔(-4)^2-(1-3^2)×2〕
=(-1000)+〔24×2〕
=(-1000)+48
=-952
-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)
=-36+0.07
=-35.93
(-3)^3-3×(-1/3)^4
=-27-3×1/8
=-27-1/27
=-27又1/27
大家说我做的对么?上面的题请大家手算,有些题乘的时候可以约分

Answer 1

(-10)^3+〔(-4)^2-(1-3^2)×2〕
=(-1000)+(16+8*2)
=-1000+32
=-968
(-3)^3-3×(-1/3)^4
=-27-3*1/81
=-27又1/27
其他都对
