#### Answer:

The derivative of a sum is the sum of the derivatives and the derivative of a constant multiple of a function is the constant times the derivative of the function.

#### Explanation:

For

#= 2x+3 d/dx(lnx)#

# = 2x+3(1/x)#

# = 2x+3/x# or, if you prefer a single ratio:

# = (2x^2+3)/x#
