|(√3)-2|+(1/5)^0-2^-1+2sin60° =2-(√3)+1-1/2+2*(√3)/2 =2-(√3) +1-1/2+(√3)=2又1/2.2.(√18)-(∏-1)^0-2cos45°+(1/4)^-1
=(3√2)-1-2*(√2)/2+4 =(3√2)+3-(√2)
=3+2√2.3.(√9)-tan60°+(√5-1)^0+|1-√3| =3-(√3)+1+(√3)-1 =34.0.25*(-cos60°)^-2-(√3-1)^0+tan60°
=1/4*1/(1/4)-1+(√3) =√35.(√12)-4cos30°+(-2)^3 =(2√3)-4*(√3)/2-8 =(2√3)-(2√3)-8 =-8.6.-(-1/2)+(√9)+(-1)^2007-cos60°
=1/2+3-1-1/2 =2. 7.(-1)^0-|tan45°-2|+2^-5*2^8 =1-|1-2|+2^(-5+8) =1-1+2^3 =8.
