1、-(-3)³+(-3)³-(-2)³×(1/3-1/2)÷(-1/6)-(-3)2、-5²-{8.5-[(-3)²-2²×(-1/4)]
1、-(-3)³+(-3)³-(-2)³×(1/3-1/2)÷(-1/6)-(-3)2、-5²-{8.5-[(-3)²-2²×(-1/4)]}÷(-1/2)²要式子,
1、-(-3)³+(-3)³-(-2)³×(1/3-1/2)÷(-1/6)-(-3)
2、-5²-{8.5-[(-3)²-2²×(-1/4)]}÷(-1/2)²
要式子,
1、-(-3)³+(-3)³-(-2)³×(1/3-1/2)÷(-1/6)-(-3)2、-5²-{8.5-[(-3)²-2²×(-1/4)]}÷(-1/2)²要式子,
-(-3)³+(-3)³-(-2)³×(1/3-1/2)÷(-1/6)-(-3)
=-(-27)+(-27)-(-8)×(-1/6)×(-6)+3
=-(-8)×1+3
=-(-8)+3
=8+3
=11
2. -5²-{8.5-[(-3)²-2²×(-1/4)]}÷(-1/2)²
=-25-{8.5-[-27-4×(-1/4)]}÷1/4
=-25-{8.5-[-27-(-1)]}×4
=-25-[8.5-(-27+1)]×4
=-25-(8.5+26)×4
=-25-138
=-163
