  • [3^(5/6) x 12^(7/12)] / [6^(2/3) x 2^(1/4)]
    = [3^(5/6) x {3 x 2^2}^(7/12)] / [{2 x 3}^(2/3) x 2^(1/4)]
    = [3^(5/6) x 3^(7/12) x 2^(14/12)] / [2^(2/3) x 3^(2/3) x 2^(1/4)]
    = 3^(5/6 + 7/12 - 2/3) x 2^(14/12 - 2/3 - 1/4)
    = 3^(10/12 + 7/12 - 8/12) x 2^(14/12 - 8/12 - 3/12)
    = 3^(9/12) x 2^(3/12)
    = 3^(3/4) x 2^(1/4)
