I'm suppose to find the exact value of this logerithm. I believe that is the base.
remember what a logarithm is, logarithms are powers.
Definition: the logarithm of a number to a given base is the power to which the base must be raised to give the number.
that is, if then
example, since we have to raise the base 2 to the power 3 to get 8
now, is the power we have to raise to to get 9. so what number is that?
I'm guessing it's 2, since we have to raise 2 to to equal 9.
so the answer is 4.
