y=2*3^x - (x³+5x)*e^x
#############################################
g=2*3^x
ln g = ln (2 * 3^x)
ln g = ln 2 + ln 3^x
ln g = ln 2 + x * ln 3
g = e^(ln 2 + x * ln 3)
g=e^(ln 2) * e^(x*ln 3)
dg/dx = e^(ln 2) * (x*ln 3)' * e^(x*ln 3)
dg/dx = e^(ln 2) * (ln 3) * e^(x*ln 3)

h=(x³+5x)*e^x
dh/dx = (x³+5x)'*e^x + (x³+5x)*(e^x)'
dh/dx = (3x²+5)*e^x + (x³+5x)*(e^x)

y=2*3^x - (x³+5x)*e^x
dy/dx = e^(ln 2) * (ln 3) * e^(x*ln 3) - (3x²+5)*e^x - (x³+5x)*(e^x)
