You cannot. You must use the formula
log in base b of a =log(a)/log(b) or
where log(a) is common logarithm of a and ln(a)= natural logarithm of a
If you had the TI84PLUS or TI84PLUS SE, you could have installed the newest OS upgrade and that upgrade uses math print which allows the user to calculate logarithms in any base directly.
