Differentiate. [math] f(x) = 3x^4 + 9sqrt(x) - 7/root[3](x^4) [/math]
  1. [math] f'(x) = 12x^3 + 9sqrt(x) + 7/(4root[3](x^3)) [/math]
  2. [math] f'(x) = 12x^3 + 9/2 sqrt(x) +21/(4root[3](x)) [/math]
  3. [math] f'(x) = 12x^3 + 9/(2sqrt(x)) + 28/(3root[3](x^7)) [/math]
  4. [math] f'(x) = 12x^3 +9 - 7/root[3](4x^3) [/math]
