Question 36638
Ok, Virus will each have a cell divison time.
TO find that time; put the equation in normal form first:
Ok first your equation might be {{{f(t)=10^t}}} not f(t)=10t
{{{5(10)^9=10^t}}}
{{{log(5(10)^9)=log10^t}}}
{{{log(5(10)^9)=tlog10}}}
{{{log5+log(10)^9=tlog10}}}
{{{log5+9log10=tlog10}}}

Like bases cancel out:
t=log5+9
Paul.
