According to the book, the answer is "2"
Can anyone prove it?

Re: Logarithms
 










I just did the maths actions without explaining, considering that you will know the steps that this exercise is going and if you don't understand anything feel free to ask. At the first line there is with base 81 and not 8 like it is being showed. I tried to fix it but I couldn't. So I hope this will help.
