问题描述:
-10-3x(-4) -2/3-2.75+1/3-1.25 -6²除以(-1/2+2) -36x(-1/18+2/3-2/9)
-12-12除以[(-1/3)²x(-18)-2²].一共五道题不要混了
答
-10-3x(-4)=-10+12=2 -2/3-2.75+1/3-1.25 =(1/3-2/3)-(2.75+1.25)=-1/3-4=-4又1/3-6²除以(-1/2+2) =-36÷(3/2)=-36×2/3=-24-36x(-1/18+2/3-2/9)=36×1/18-36×2/3+36×2/9=2-24+8=-14-12-12...1.-5+3-4+10 2.(-7)-6+|-3|(-8)你好,请点击我头像右侧法咨询向我提问即可
