$$f(x) = (\frac{4x^2+ 2xe^x}{4x})^{2/5}$$$$f'(x) = \frac{2}{5}(\frac{4x^2+ 2xe^x}{4x})^{\frac{2}{5} -1 }(\frac{4x(8x + 2(e^x + xe^x)) - 4(4x^2+ 2xe^x) }{(4x)^2})$$

lochana · Answer

hmm.. it takes some work, this is what you should simplify.

g(x) = ln(3x^3 + 3x^5)

d/dx of lnu = u'/u

g'(x)  = 9x^2 + 15x^4 /3x^3 + 3x^5

3x^2(3 + 5x^2)/ 3x^2(x + x^2) = 3+5x^2 / x+x^2

Thank you! TrojanPoem, is that the complete solution?

I couldn't give you both a medal, so I became a fan of one of you instead.
