Here, we show you a step-by-step solved example of derivative of logarithmic functions. This solution was automatically generated by our smart calculator:
To derive the function $x^{\left(x+2\right)}$, use the method of logarithmic differentiation. First, assign the function to $y$, then take the natural logarithm of both sides of the equation
Apply natural logarithm to both sides of the equality
Using the power rule of logarithms: $\log_a(x^n)=n\cdot\log_a(x)$
Derive both sides of the equality with respect to $x$
Apply the product rule for differentiation: $(f\cdot g)'=f'\cdot g+f\cdot g'$, where $f=x+2$ and $g=\ln\left(x\right)$
The derivative of the natural logarithm of a function is equal to the derivative of the function divided by that function. If $f(x)=ln\:a$ (where $a$ is a function of $x$), then $\displaystyle f'(x)=\frac{a'}{a}$
The derivative of the natural logarithm of a function is equal to the derivative of the function divided by that function. If $f(x)=ln\:a$ (where $a$ is a function of $x$), then $\displaystyle f'(x)=\frac{a'}{a}$
The derivative of the linear function is equal to $1$
The derivative of the linear function is equal to $1$
Multiply the fraction by the term
Any expression multiplied by $1$ is equal to itself
Multiply the fraction by the term
The derivative of the constant function ($2$) is equal to zero
The derivative of the linear function is equal to $1$
The derivative of a sum of two or more functions is the sum of the derivatives of each function
Multiply both sides of the equation by $y$
Substitute $y$ for the original function: $x^{\left(x+2\right)}$
The derivative of the function results in
