I found that it is equal to zero:

You may use the definition of log:
$log_ba=x$
so that: $a=b^x$

we now need to find our $x$ in:
$log_3(1)=x$

using our definition we see that the only possible value for $x$ is zero because:
$1=3^0$

$log_3 1 = 0$

Written in log form, the question being asked is,"

"1 is which power of 3? " $3^0 =1$

Or

"Using a base of 3, what index will give 1 as the answer?"
$3^0 =1$

Log form and index form are interchangeable.

$log_3 1 = x " " rArr 3^x = 1$

$x = 0$
