#### Answer

difference;
$\log_5{25}$;
$\log_5{125}$

#### Work Step by Step

RECALL:
$\log{(\frac{a}{b})}=\log{a} - \log{b}$
This means that the logarithm of a quotient of two numbers is equal to the difference of of the logarithms of each number.
Therefore, the missing expressions in the given statement are (in order):
difference;
$\log_5{25}$;
$\log_5{125}$
