(3√48-2√27)÷√3+√2÷(3-√3)
√12-√1/2-(√1/8-√27)
1/2√6÷4√1/12*(-2/3√3/2)

(3√48-2√27)÷√3+√2÷(3-√3)√12-√1/2-(√1/8-√27)1/2√6÷4√1/12*(-2/3√3/2)
(3√48-2√27)÷√3+√2÷(3-√3)
=(12√3-6√3)÷√3+√2(3+√3)÷(9-3)
=6√3÷√3+(3√2+√6)÷6
=6+1/2√2+1/6√3
√12-√1/2-(√1/8-√27)
=2√3-1/2√2-1/4√2+3√3
=5√3-3/4√2
1/2√6÷4√1/12*(-2/3√3/2)
=1/2√6÷2/3√3*(-1/3√6)
=3/4√2*(-1/3√6)
=-1/4√12
=-1/2√3
