化简:2(√3-√2)+(1/√2+1)-(2/√3+1)化简:2(√3-√2)+(1/√2+1)-(2/√3+1)急求急求急求!

化简:2(√3-√2)+(1/√2+1)-(2/√3+1)化简:2(√3-√2)+(1/√2+1)-(2/√3+1)急求急求急求!
化简:2(√3-√2)+(1/√2+1)-(2/√3+1)
化简:2(√3-√2)+(1/√2+1)-(2/√3+1)急求急求急求!

化简:2(√3-√2)+(1/√2+1)-(2/√3+1)化简:2(√3-√2)+(1/√2+1)-(2/√3+1)急求急求急求!
原式=:2√3-2√2+(√2-1)/(√2+1)(√2-1)-2(√3-1)/(√3+1)(√3-1)
=:2√3-2√2+(√2-1)/(2-1)-2(√3-1)/(3-1)
=2√3-2√2+√2-1-2√3+2
=-√2+1

将括号打开
2√3 -2√2 +√2/2 +1-2√3-1=-3√2/2


2(√3-√2)+(1/√2+1)-(2/√3+1)
=2√3-2√2+√2-1-√3+1
=2√3-√3-2√2+√2-1+1
=√3-√2

2(√3-√2)+(1/√2+1)-(2/√3+1)
=2√3-2√2+√2/2+1-2√3/3-1
=4√3/3-3√2/2
不懂再问,望采纳,谢谢
