Question

Log6 90 - log6 2,5........

Answer 1

Log6 90-log6 2,5=
(Пользуясь свойством сложения логарифмов и определением логарифма, получим)
=log6 (90:2,5)= log6 36=2

Answer 2

Using the logarithmic identity that says:

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

We can simplify the expression:

log6 90 - log6 2.5 = log6 (90/2.5)

Now we just need to divide 90 by 2.5:

log6 (90/2.5) = log6 36

Therefore,

log6 90 - log6 2.5 = log6 36.
