2乘以根号3乘以三次根号6乘以六次根号12除以(三次根号4乘以三次根号3)??
=2*3^(1/2)*6^(1/3)*12^(1/6)/[4^(1/3)*3^(1/3)]
=2*3^(1/2)*(2*3)^(1/3)*(2*2*3)^(1/6)/[(2*2)^(1/3)*3^(1/3)]
=2*3^(1/2)*2^(1/3)*3^(1/3)*2^(1/6)*2^(1/6)*3^(1/6)/[2^(2/3)*3^(1/3)]
=2^(1+1/3+1/6+1/6-2/3)*3^(1/2+1/3+1/6-1/3)
=2*3^(2/3)
=2乘以三次根号(9)
=2*3^(1/2)*6^(1/3)*12^(1/6)/[4^(1/3)*3^(1/3)]
=2*3^(1/2)*(2*3)^(1/3)*(2*2*3)^(1/6)/[(2*2)^(1/3)*3^(1/3)]
=2*3^(1/2)*2^(1/3)*3^(1/3)*2^(1/6)*2^(1/6)*3^(1/6)/[2^(2/3)*3^(1/3)]
=2^(1+1/3+1/6+1/6-2/3)*3^(1/2+1/3+1/6-1/3)
=2*3^(2/3)
=2乘以三次根号(9)

我打错了最后是三次根号27

最后是24吧
原式=2*3^(1/2)*6^(1/3)*12^(1/6)÷(4^(1/3)*24^(1/3)
=2*3^(1/2)*2^(1/3)*3^(1/3)*2^(1/3)*3^(1/6)÷(2^(2/3)*2*3^(1/3))
=2^(1+1/3+1/3-2/3-1)*3^(1/2+1/3+1/6-1/3)
=2^0*3^(2/3)
=3次根号9
原式=2*3^(1/2)*6^(1/3)*12^(1/6)÷(4^(1/3)*24^(1/3)
=2*3^(1/2)*2^(1/3)*3^(1/3)*2^(1/3)*3^(1/6)÷(2^(2/3)*2*3^(1/3))
=2^(1+1/3+1/3-2/3-1)*3^(1/2+1/3+1/6-1/3)
=2^0*3^(2/3)
=3次根号9
