Dear Student, By the defination of the lograthmic, the log function is not defined for the negative values of input variable. i.e. the domain for the log function is the non-negative real numbers. Thanks.

$2\log (-5)$ $is$ $not$ defined as input is -ve

But $\log ((-5)^{2})$ is defined as input is +ve

And also $2\log (-5) \neq \log ((-5)^{2}) = \log (5^{2})) = 2\log(5)$
