2.(3x^4)^-3        3.(16)^3/4             4. x^1/2times x^3/2
  --------
    y                                      ----------------
                                               x^-1

----------------------------------------------------------------
#2. = 1/[(27x^12)y]
------------------
#3  = 2^3 = 8
--------------------
#4  = x^(1/2 + 3/2)/x^-1

= x^2*x = x^3
