Apply the product rule for differentiation: $(f\cdot g)'=f'\cdot g+f\cdot g'$, where $f=x^4$ and $g=\log_{5}\left(x\right)$

$\frac{d}{dx}\left(x^4\right)\log_{5}\left(x\right)+x^4\frac{d}{dx}\left(\log_{5}\left(x\right)\right)$

Learn how to solve differential calculus problems step by step online. Find the derivative of x^4log5(x). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=x^4 and g=\log_{5}\left(x\right). The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. We can find the derivative of a logarithm of any base using the change of base formula. Before deriving, we must pass the logarithm to base e: \log_b(a)=\frac{\log_x(a)}{\log_x(b)}. The derivative of a function multiplied by a constant (\frac{1}{\ln\left(5\right)}) is equal to the constant times the derivative of the function.

Final answer to the problem

$4x^{3}\log_{5}\left(x\right)+\frac{x^{3}}{\ln\left(5\right)}$

Main Topic: Differential Calculus

The derivative of a function of a real variable measures the sensitivity to change of a quantity (a function value or dependent variable) which is determined by another quantity (the independent variable). Derivatives are a fundamental tool of calculus.
