Question: Find \(y'\) when

(a) \(y=1-{{x}^{2}}{{e}^{x}}\)

(b) \(y=3{{e}^{-5{{x}^{2}}+2x}}\)

(c) \(y={{\left( {{e}^{2x}}+1 \right)}^{5}}\)

(d) \(y=5\ln 3x\)

(e) \(y=\ln \left( \frac{{{x}^{2}}+1}{x+2} \right)\)

(f) \(y={{8}^{3x}}\)

(g) \(y={{x}^{4}}{{4}^{x}}\)

(h) \(y=\frac{\ln \left( {{x}^{3}}-4x \right)}{{{3}^{2x-1}}}\)
