HELP!
[2+(根号2)/2-(根号2)]^2+[2-(根号2)/2+(根号2)]
[2+(根号2)/2-(根号2)]^2+[2-(根号2)/2+(根号2)]^2
题错了 不好意思~^^;

最后一个有没有^2呵呵
设2=A,(根号2)/2-(根号2)=B
则[2+(根号2)/2-(根号2)]^2=A+B
-(根号2)/2+(根号2)= -B
则,2-(根号2)/2+(根号2)=A-B
原式=(A+B)^2-(A-B)^2=2(A^2+B^2)
=2{2^2+[(√2/2)-√2]^2}
=2{4+[(1/2)-2*√2/2*√2+2]}
=2{4+(1/2-2+2)}
=2(4+1/2)=9
这样算就不会晕了
=[2-(根号2)/2]^2+[2+(根号2)/2]
=4-(根号2)+1/2+2+(根号2)/2
=(13/2)-(根号2)/2
=(13-根号2)/2
根号8+根号0.5-根号2*根号2/根号3
(根号48+根号27-根号12)/(根号2+根号3)
计算:根号45 +(根号3)/2 + 根号18 - 根号80 + 根号(根号2 - 根号5)^2
化简:|1-根号2|+|根号2-根号3|+|根号3-根号4|+.+|根号2011-根号2012|

|2×根号2-根号3|-根号2
(根号9+根号2) -2×根号2
|根号2 -根号3|-2根号2
|根号2-根号16|-根号2^2
根号2-根号8+3根号18
根号8*(根号2-根号二分之一)
根号8+根号32-根号2等于
根号18/根号8*根号27/2
根号2+根号3乘以根号6
-根号18+根号32+根号2
