回答1:

-(-3)²×(-1)-8×(-1/2)³×l-2-3l=-9×(-1)-8×(-1/8)×5=9+5=14

-1⁴-(1-0.5)×1/3×[2-(-3)²]=-1-1/2×1/3×[-7]=1+7/6=13/6
[(-1/6)-(-5/12)+2/12]×(-60)=10-25+10=-25

回答2:

-(-3)²×(-1)-8×(-1/2)³×l-2-3l=-9×(-1)-8×(-1/8)×5=9+5=14

-1⁴-(1-0.5)×1/3×[2-(-3)²]=-1-0.5×(1/3)×(-7)=-1+7/6=1/6

[(-1/6)-(-5/12)+2/12]×(-60)=(-1/6)×(-60)-(-5/12)×(-60)+(2/12)×(-60)=10-25-10=-25

回答3:

-(-3)²×(-1)-8×(-1/2)³×l-2-3l

=-9*(-1)-8*(-1/8)*5
=9+5
=14
-1⁴-(1-0.5)×1/3×[2-(-3)²]

=-1+7/6
=1/6
[(-1/6)-(-5/12)+2/12]×(-60)
=-25
