We begin by using the following log rule to simplify our question:
log ab = log a + log b
We can write our question as:
y = log26x = log26 + log2x
The first term, log26, is a constant, so its derivative is 0.
The derivative of the second term is as follows, using our formula:
The term on the top, log2e, is a constant. If we need a decimal value, we can work it out using change of base as follows:
