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:

`(dy)/(dx)=(log_2e) (1/x)=(log_2e)/x`

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:

`log_2e=(log_10e)/(log_10 2)=1.442695041`
