Question 1180107
.


This problem is constructed by its composer according the following principle


<pre>
    Push all known words and formulas into one box.
    Do not care about the meaning.
    and let the reader spends his (or her) time,
    while we will laugh on him.
</pre>


I know the method on how to solve it.



This method is &nbsp;FILTERING &nbsp;OUT &nbsp;ALL &nbsp;UNNECESSARY &nbsp;WORDS.



Following this method, &nbsp;I read the problem in this way


&nbsp;&nbsp;&nbsp;&nbsp;1)  &nbsp;&nbsp;We are given the initial number of bacteria &nbsp;(8)


&nbsp;&nbsp;&nbsp;&nbsp;2)  &nbsp;&nbsp;We are given the doubling time &nbsp;(6 &nbsp;hours)


&nbsp;&nbsp;&nbsp;&nbsp;3)  &nbsp;We are asked about the time getting &nbsp;N = 7681 bacteria.



**************************************************************

&nbsp;&nbsp;&nbsp;&nbsp;It is the standard problem on exponential growth.

**************************************************************



<pre>
    N(t) = 8*2^(t/6)


    7681 = 8^2^(t/6)


    {{{7681/8}}} = 2^(t/6)


    960.125 = 2^(t/6)


    {{{log(2,(960.125))}}} = {{{t/6}}}     logarithm base 2


    t = {{{6*log(2,(960.125))}}} = 59.44 hours.      <U>ANSWER</U>
</pre>

Solved.

The rest of the non-necessary words in the post is &nbsp;GARBAGE.



In simple terms, &nbsp;posting such &nbsp;"problems" &nbsp;is mocking tutors.




Next time I will not allow for such gibberish to come to the forum:


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;as soon as I will see it, &nbsp;I will delete it &nbsp;(without explanations).
