.
Please help me solve this question. What is the average of 3^22, 3^23 and 3^24
~~~~~~~~~~~~~~~~~~~~~~~



        Calculations in the post by the other tutor are incorrect.

        I came to bring a correct solution.



<pre>
The average of 3^22, 3^23 and 3^24 is

    {{{(1/3)*(3^22+3^23+3^24)}}} = {{{3^22*(1/3)*(1+3+9)}}} = 13*3^21.    <U>ANSWER</U>

Solved correctly.
