Answer 1

Use properties of logs

$log( \frac{5x}{4y} ) \\ log(5x) - log(4y) \\( log(5) + log(x)) -( log(4) + log(y) )$

distribute the negative

your answer is B

Answer 2

Because it is a fraction ( division) rewrite as:

log (5x) - log (4y)

Rewrite log 5x as log 5 + log x

Rewrite log 4y as log 4 + log y

Now you have log 5 + log x  - log 4 + log y

Apply distributive property:

log 5 + log x - log 4 - log y

The answer is B.
