$\lim_{x\to0}\left(\frac{\frac{d}{dx}\left(5x\right)}{\frac{d}{dx}\left(\ln\left(1-3x\right)\right)}\right)$

Learn how to solve limits problems step by step online. Evaluate the limit of (5x)/(ln(1-3*x) as x approaches 0. If we try to evaluate the limit directly, it results in indeterminate form. Then we need to apply L'Hôpital's rule. The derivative of the linear function times a constant, is equal to the constant. 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 a sum of two functions is the sum of the derivatives of each function.
