# The way we write ln(x) to the power of a

johann1301
I have learned that (cos x)a can be written as cosax. And like wise for sin x and tan x.

How come we don't write (ln x)a as lnax or (log x)a as logax?

I just think it seems smarter when its written with as few symbols as possible.

(Or perhaps its just my textbook which don't write it this way?)

LOTS of textbooks use that convention. I will go as far as to say it is the most common convention.

Personally, I hardly ever see logs with powers (except in a couple of circumstances), while trigs with powers (especially squared) are a common occurrence.
