Computing the derivative of a logarithm function using the chain rule.

$\frac{d}{d x} [\ln (6 x^{3} + 5)] = \frac{1}{6 x^{3} + 5} \times \frac{d}{d x} [6 x^{3} + 5]$

Decomposing the function for the chain rule.

$\frac{d}{d x} [\ln (6 x^{3} + 5)] = \frac{d}{d x} [\ln (x)] \times \frac{d}{d x} [6 x^{3} + 5]$

Computing the derivative of a natural logarithm function.

$\frac{d}{d x} [\ln (x)] \times \frac{d}{d x} [6 x^{3} + 5] = \frac{1}{x} \times \frac{d}{d x} [6 x^{3} + 5]$

Substituting the variable back into the function.

$\frac{1}{x} \times \frac{d}{d x} [6 x^{3} + 5] = \frac{1}{6 x^{3} + 5} \times \frac{d}{d x} [6 x^{3} + 5]$

Applying the sum rule of derivatives.

$\frac{1}{6 x^{3} + 5} \times \frac{d}{d x} [6 x^{3} + 5] = \frac{1}{6 x^{3} + 5} \times (\frac{d}{d x} [6 x^{3}] + \frac{d}{d x} [5])$

Applying the product rule of derivatives.

$\frac{1}{6 x^{3} + 5} \times (\frac{d}{d x} [6 x^{3}] + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times ((\frac{d}{d x} [6] \times x^{3} + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5])$

The derivative of a constant value is always zero.

$\frac{1}{6 x^{3} + 5} \times ((\frac{d}{d x} [6] \times x^{3} + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times ((0 x^{3} + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5])$

Multiplying a number by zero always results in zero.

$\frac{1}{6 x^{3} + 5} \times ((0 x^{3} + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times ((0 + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5])$

Adding zero to a number, which does not change its value.

$\frac{1}{6 x^{3} + 5} \times ((0 + 6 \times \frac{d}{d x} [x^{3}]) + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times (6 \times \frac{d}{d x} [x^{3}] + \frac{d}{d x} [5])$

Computing the derivative of x raised to the power of n.

$\frac{1}{6 x^{3} + 5} \times (6 \times \frac{d}{d x} [x^{3}] + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times (6 \times (3 x^{3 - 1}) + \frac{d}{d x} [5])$

Subtracting one from a number.

$\frac{1}{6 x^{3} + 5} \times (6 \times (3 x^{3 - 1}) + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times (6 \times (3 x^{2}) + \frac{d}{d x} [5])$

Multiplication can be grouped differently, but the result remains the same.

$\frac{1}{6 x^{3} + 5} \times (6 \times (3 x^{2}) + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times ((6 \times 3) \times x^{2} + \frac{d}{d x} [5])$

Multiplying two integers together.

$\frac{1}{6 x^{3} + 5} \times ((6 \times 3) \times x^{2} + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times (18 x^{2} + \frac{d}{d x} [5])$

The derivative of a constant value is always zero.

$\frac{1}{6 x^{3} + 5} \times (18 x^{2} + \frac{d}{d x} [5]) = \frac{1}{6 x^{3} + 5} \times (18 x^{2} + 0)$

Adding zero to a number, which does not change its value.

$\frac{1}{6 x^{3} + 5} \times (18 x^{2} + 0) = \frac{1}{6 x^{3} + 5} \times (18 x^{2})$

Simplifying the arithmetic expressions.

$\frac{1}{6 x^{3} + 5} \times (18 x^{2}) = \frac{18 x^{2}}{6 x^{3} + 5}$
