WebWhen we take the logarithm of a number, the answer is the exponent required to raise the base of the logarithm (often 10 or e) to the original number. For example log base 10 of 100 is 2, because 10 to the second power is 100. ... Derivatives of Logarithms and Exponentials. The derivatives of the natural logarithm and natural exponential ... WebJun 30, 2024 · Example \(\PageIndex{5}\): Using Properties of Logarithms in a Derivative. Find the derivative of \(f(x)=\ln\left(\dfrac{x^2\sin x}{2x+1}\right)\). Solution. At first glance, taking this derivative appears rather complicated. However, by using the properties of logarithms prior to finding the derivative, we can make the problem much simpler.
