Final answer:
The product rule for logarithmic equations states that the logarithm of a product of two numbers is equal to the sum of the logarithms of the individual numbers. Option c. 10 ln(4x) = 10 ln(4) - 10 ln(x) illustrates the product rule for logarithmic equations.
Step-by-step explanation:
The product rule for logarithmic equations states that the logarithm of a product of two numbers is equal to the sum of the logarithms of the individual numbers.
In this case, option c. 10 ln(4x) = 10 ln(4) − 10 ln(x) illustrates the product rule for logarithmic equations. The logarithm of the product 4x is equal to the sum of the logarithms of 4 and x.
