[tex]x^{log_b (x)}[/tex] gives

Use "\log" instead of "log" : x^{\log n-1} gives . However is ambiguous because it can mean or ; you'd better add parenthesis.

you can also type \; to make a space

e.g. x^{log\;n-1}

or "~" or "\ ", or ...

I have four different space codes for math mode on my quick reference card, and I know that that list is not exhaustive.

CB

\, (backslash + comma) gives a small space, \ (backslash + space) gives a medium space while \quad gives a large space.

Code:

a \, b
a \ b
a \quad b

The small space is particularly useful for formatting integrals:

Code:

\int \sin x \, dx

certainly looks neater than
