Question

A student claims that it is enough to have only the product rule of logarithms, and that other rules can be derived from it, including the power rule. For example, the student derives the power rule from the product rule as follows:

log(xy) = log(x) + log(y) → log(x")= log(x x x × x x · …x x) = log(x) + log(x) +
n log(x)
Give an example where the above argument is not valid.
