By definition, if :

[tex]a^y = b[/tex]

[tex]y = log_a b[/tex]

We highlight the following elements:

a = Base of the logarithm;
b = logarithmand or antilogarithm
y = logarithm

Therefore:

Note that since the base was not specified, we know that it is equal to 10.

[tex]y = log_a b[/tex]
[tex]y = log_{10} (x-3)[/tex]
[tex]10^y = (x-3)[/tex]

Answer:

Base of the logarithm = 10
