To derive the function $x^{7x}$, 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 $x$
The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function
Apply the product rule for differentiation: $(f\cdot g)'=f'\cdot g+f\cdot g'$, where $f=x$ and $g=\ln\left(x\right)$
The derivative of the linear function is equal to $1$
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 $1$
Multiply the fraction by the term
Multiply both sides of the equation by $y$
Substitute $y$ for the original function: $x^{7x}$
The derivative of the function results in
