Question 1140157
{{{y=ab^x}}}


{{{300=100b^2}}}
{{{b^2=3}}}
{{{b=sqrt(3)}}}


{{{highlight(y=100(sqrt(3))^x)}}}



Population size after 10 days:
{{{(sqrt(3))^10}}}

{{{((sqrt(3))^2)^5}}}

{{{3^5}}}

{{{27*9}}}

{{{highlight(243)}}}



How much is the doubling time?
{{{2=1*(sqrt(3))^x}}}
and you can finish this.  Find this x.
