-2²-【-3】*(-1/3)+(-3)²除以9/2+(-1/2)²*(2/3)²-(-1)的15次方
问题描述:
-2²-【-3】*(-1/3)+(-3)²除以9/2+(-1/2)²*(2/3)²-(-1)的15次方
-2²+(-3)*【(-4)²+2】-(-3)³除以3
【55-(7/9-11/12+1/6)*(-6)²】/(-3)³
-(2/3)²乘3-2*(-2/3)+2/3-4*(-3/2)²
【11*2-【3/3】-(-3)²-3³】除以3/4
20/9*(-3/2)³-(-1.2)²除以0.4²
答
-2²+(-3)*【(-4)²+2】-(-3)³除以3
=-4-3*(16+2)+27/3
=-4-54+9
=-49
【55-(7/9-11/12+1/6)*(-6)²】/(-3)³
=[55-(7/9-11/12+1/6)*36]÷(-27)
=(55-28+33-6)÷(-27)
=54÷(-27)
=-2
-(2/3)²乘3-2*(-2/3)+2/3-4*(-3/2)²
=-4/9×3+4/3+2/3-4×9/4
=-4/3+6/3-9
=2/3-9
=-8又3分之1
【11*2-【3/3】-(-3)²-3³】除以3/4
=(22-1-9-27)÷3/4
=-15×4/3
=-20
20/9*(-3/2)³-(-1.2)²除以0.4²
=20/9×(-27/8)-1.44÷0.16
=-15/2-9
=-16.5还差一道-2²-【-3】*(-1/3)+(-3)²除以9/2+(-1/2)²*(2/3)²-(-1)的15次方=-4-1+9×2/9+1/4×4/9+1=-5+2+1/9+1=-2+1/9=-17/9
