刚才好象也是你,把2^2000打成2^200
【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷|-4÷2*(1/2)^2|
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷|-4÷2*(1/4)|
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷|-4*(1/2)*(1/4)|
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷|-2*(1/4)|
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷|-1/2|
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷1/2
=【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】÷1/2
=2【(-1)^3÷2/9+2^200*(-0.5)^2001-3^3*(-3/2)^2】
=2(-1÷2/9-0.5-9*9/4)
=2(-9/2-0.5-81/4)
=-9-1-81/2
=-101/2
