it's probably under the catalog button (lets you select from a list of functions and instructions) pg. 465 of the manual (below)
here's the manual for your calc:

here is a possible solution

Base 10
The TI-89 does not have a logarithm base 10 key. However, one can use logarithm base 10 from the catalog. Press CATALOG to access the catalog. To navigate to log( , press L, then , then press the blue down arrow on the thumb pad, then press the blue down arrow 5 times to select log( . Press . Enter the number of interest, then press the right parenthesis.
Another simple solution would just be to use the principles of base changing with logarithms.
LN(Whatever number)/LN(Whatever base) will give you the log of that number to the specified base.
Ie LN(100)/LN(10) Will give you Log(100), or 2.
try the manual maybe?
