Question 1192445
<pre>
N(0) = 5    <--- starting time, 5 tribbles
N(1) = 5*3  <--- after 1hr, they triple to 5*3 = 15
N(2) = 5*3*3  <---- at 2hr mark, they've tripled again (5*3)*3 = 45
 :
N(k) = {{{5*3^k }}}  <--- after k hours, there will be this many tribbles


After 8hrs:  N(8) = {{{5*3^8 }}} = {{{ 5*6561 }}} = {{{ highlight(32805) }}}
