Answer 1

Ответ:

Пошаговое объяснение:

log_5 7  -  log_5 (7/25)  =  log_5 (7 : 7/25)  =  log_5 25  =  2

Answer 2

To solve this problem, we can use the following rules of logarithms:

log a - log b = log (a/b) (Rule 1)

log a^n = n log a (Rule 2)

Using Rule 1, we can simplify the expression as follows:

log5 7 - log5 (7/25) = log5 (7/(7/25))

= log5 (25)

= log5 (5^2)

= 2

Therefore,

log5 7 - log5 7/25 = 2.
