答案和解析
-1/4+(-2)^2 =15/4
-(-3)^2+(-2)^3 =-9-8=-17
(3/4*16)^2=12*12=144
(3/4)^2*(-16^2) =-12*12=-144
(-1又1/2-0.5)^2 =4
(+1又1/2)^2+0.5^2 =9/4+1/4=5/2
(-2)^5*5^5 =(-10)^5=-10000
(5^2-7^2)*(-1)^3 =24
(6^2-7^2)/(-1)^4 =-42
-5又1/8-(1/3-2又1/8)+1又1/3=-2
(-3)^2*[-2/3+(-5/9)]=9*(-11/9)=-11
-3又1/2*5又3/5/(-2)*5/4= 49/4
-3^2-(-5)^3*(-2/5)^2 =12
1又7/8+(-4又1/2+3/4)*(-3/4) =75/16
-1^4-1/6/[2-(-3)^2] =-1+1/42=-41/42
-3^2+(-3)^2+3*(-6)=-9+9-18=-18
(-2又3/4)/1又1/8-(-6)*(1+2/3-(-2)^3
=(-11/4)/(9/8)+10+8
=-22/9+18
=140/9
-3^2*(-4/27)+(-3)^3/2又1/4*(-2/3)^2+4
=4/3+9/(9/4)*(4/9)+4
=4/3+16/9+4
=64/9
[2又1/2-(3/8+1/6-3/4)*24]/(-3^2+4)*(-1)^2009
=(15/2)/(-5)*(-1)
=3/2
-32又16/25/(-8*4)-(1/2+2/3-3/4-11/12)*(-24)
=25.5+12
=37.5
-4.165*4/7+7.665*4/7-(7/18-5/6+7/9)/(-1/6)
=3.5*4/7+7/3-5+14/3
=2-5+21/3
=4
