What is the derivative of #ln sqrt(2x+1)#? Calculus Basic Differentiation Rules Chain Rule 1 Answer Jim H Nov 1, 2017 #lnsqrt(2x+1) = ln((2x+1)^1/2) = 1/2 ln(2x+1)# Explanation: So, the derivative is #1/2[1/(2x+1) * d/dx(2x+1) = 1/2 [1/(2x+1) * 2] = 1/(2x+1)# Answer link Related questions What is the Chain Rule for derivatives?
