Find dydx Do not simplify the expressions after finding deri

Find dy/dx. Do not simplify the expressions after finding derivatives. Y=x/{x^2+9} +(x^3+2x^2)(3x-1)

Solution

I am allowed to answer only 1 question at a time

y = ln (x^6) + log3 (x) + 10*e^x + 5^x
dy/dx = 1/(x^6) *d/dx(x^6) + 1/x + 10*e^x + 5^x * log 5
= 6*x^5/x^6 + 1/x + 10*e^x + 5^x * log 5
= 7/x + 10*e^x + 5^x * log 5
