Determine the Derivative of f(x) = 22 + 25 In x

f'(x) = d(22)/dx + (25) (d (ln x) / dx) + (ln x ) (d(25)/dx)
f'(x) = 0 + 25 (1/x) + (ln x)(0)
f'(x) = 25/x

d[f(x)]=25*(1/x)

since with derivatives, values without variables have no relevance, so

f'(x) = (25lnx)

(lnx)' = 1/x

f'(x) = 25 * (1/x)
f'(x) = (25/x)
