1.(-1/3)^-2+(√3-1)^2-√27-(√2-1)^0 2.(4√3-2√12+3√18)÷(-2√1/3)

1.(-1/3)^-2+(√3-1)^2-√27-(√2-1)^0 2.(4√3-2√12+3√18)÷(-2√1/3)
1.(-1/3)^-2+(√3-1)^2-√27-(√2-1)^0 2.(4√3-2√12+3√18)÷(-2√1/3)

1.(-1/3)^-2+(√3-1)^2-√27-(√2-1)^0 2.(4√3-2√12+3√18)÷(-2√1/3)
(-1/3)^-2+(√3-1)^2-√27-(√2-1)^0
=9+3-2√3+1-3√3-1
=12-5√3
(4√3-2√12+3√18)÷(-2√1/3)
=（4√3-4√3+9√2）÷（-2/3√3）
=9√2÷-2/3√3
=27/2√2/3
=9/2√6
