就是几道数学题哈 (1)√6x2√3-√24/√3 (2) (√27-2√18)/√6 (3)√32-5√1/2+6√1/8

(1)0
(2)(3√2)/2-2√3
(3)3√2

1 ; =2√(3x3x2)-√(2x2x2x3x3)
=6√2-6√2
=0
2 √(27\6)-2√3
=3√2/2-2√3
3

(1)√6x2√3-√24/√3=6√2-2√2=4√2
(2) (√27-2√18)/√6 =√(9/2)-2√3=(3√2)/2-2√3
(3)√32-5√1/2+6√1/8=4√2-5√2/2+3/2√2=3√2

(1)0
(2)9根号2-12根号3
(3)3根号2

(1)
√6×2√3-√24/√3
= 6√2 - 2√2
= 4√2
(2)
(√27-2√18)/√6
= (3√3 - 6√2) /(√2√3)
= 3/√2 - 6/√3
= 3√2/2 - 2√3
(3)
√32-5√(1/2)+6√(1/8)
= 4√2 - 5√2/2 + 3√2/2
= √2(4 - 5/2 + 3/2)
= 3√2
