化简2根号(6-3根号3)
2√(6-3√3)
=2√[3(2-√3)]
=2√3*√[(4-2√3/2)]
=2√3*√[(√3-1)^2/2]
=2√3(√3-1)/√2
=√6(√3-1)
=3√2-√6.
=2√[3(2-√3)]
=2√3*√[(4-2√3/2)]
=2√3*√[(√3-1)^2/2]
=2√3(√3-1)/√2
=√6(√3-1)
=3√2-√6.
化简:根号(2+根号3)分之根号2+根号6
化简(8+2根号5-根号10-根号6)/(根号5+根号3-根号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|
化简:|1-根号2|+|根号2-根号3|+|根号3-根号4|+.+|根号99-根号100|
化简:2根号3+根号6-3根号2除以2+根号2-根号6
化简:1+根号2-根号3分之3+2根号2-根号3-根号6
化简:(根号2)-1/1+根号3(根号3-根号6)+根号8
化简:3+根号6除以5根号3-2根号12-根号32+根号50
化简:根号24-根号1/2+2根号2/3-根号1/8-根号6
化简2+根号6+根号10+根号15分之根号2+根号3
根号2+根号3乘以根号6
根号6×根号2 /根号3等于多少?(化简)
