计算题5/2-|-2/3|-(4/9)-(-2.75)=-1的4次方-6/1x[2-(-3)的2次方]计算题5/2-|-2/3|-(4/9)-(-2.75)=-1的4次方-6/1x[2-(-3)的2次

计算题5/2-|-2/3|-(4/9)-(-2.75)=-1的4次方-6/1x[2-(-3)的2次方]
计算题
5/2-|-2/3|-(4/9)-(-2.75)=
-1的4次方-6/1x[2-(-3)的2次方]

计算题5/2-|-2/3|-(4/9)-(-2.75)=-1的4次方-6/1x[2-(-3)的2次方]
5/2-|-2/3|-(4/9)-(-2.75)=
=5/2-2/3-4/9+2.75
=5/2+11/4-(2/3+4/9)
=21/4-10/9
=149/36
-1的4次方-6/1x[2-(-3)的2次方]
=-1-1/6×(2-9)
=-1+7/6
=1/6
