Question 1203303
<br>
This is too nice a problem for us to solve it for you.  You should have the pleasure of finding your way to the answer yourself.  I will just get you started.<br>
If what I show you doesn't yet help you reach the final answer, then post a "thank you" saying you need more help.<br>
And of course if the little I show you below allows you to finish the problem yourself, I would very much like to see a "thank you" note from you saying so.<br>
By the way, the little you have been able to figure out to do is a BIG first step!<br>
Here is all I am going to show you....<br>
{{{f(1)=log(1)/log(1*2005)}}}<br>
{{{f(2005) = log(2005)/log(2005*1)}}}<br>
Now find the sum of f(1) and f(2005) and use basic rules of logarithms to simplify....<br>
Then a little logical reasoning and simple mental arithmetic should lead you to the final answer.<br>
Best of luck.  I hope to hear from you one way or another...!<br>
Note: After you finish the problem, I will post a full answer so other students in the future can see it.<br>

Thanks for the note of thanks.<br>
It looks as if you were able to finish the problem on your own using my suggestion, even though two other tutors posted full solutions....<br>
Good job!<br>
