Remind that the derivative of the composition of functionsf(g(x))f(g(x)) is: fx(g(x))=fg(g(x))g(x)f'_x(g(x))=f'_g(g(x))g'(x). Thus, we get: y=4(arctan3(3x5))(3x5)1+9x10=60x4arctan3(3x5)1+9x10.y'=\frac{4(\arctan^3(3x^5))(3x^5)'}{1+9x^{10}}=\frac{60x^4\arctan^3(3x^5)}{1+9x^{10}}.

The answer is: y=60x4arctan3(3x5)1+9x10y'=\frac{60x^4\arctan^3(3x^5)}{1+9x^{10}}
