Use the properties of logarithms and the values below to find the logarithm indicated.

-2B

Step-by-step explanation:

log₉ (1/16)

log₉ (16^-1)

log₉ (4^-2)

Using exponent property of logs:

-2 log₉ (4)

Substituting:

-2B

-2B

(I guess this is what you are looking for; didn't need A or C).

Step-by-step explanation:

It seems like to wants us to to find in terms of .

First thing I'm going to do is rewrite    using the quotient rule.

The quotient rule says:

So that means for our expression we have:

Second thing I'm going to do is say that .

Now I know 16 is 4 squared so the third thing I'm going to do is replace 16 with 4^2 with aim to use power rule.

The fourth thing I'm going to is apply the power rule. The power rule say . So I'm applying that now:

So we are given that is . So this is the last thing I'm going to do is apply that substitution:

its 69.420
