Question 636923
<pre>
{{{2*"f(2)"/3}}}

f(x) = {{{(x^2+5)/(4^x-3)}}}

First we find f(2) from f(x) by substituting 2 for x
and simplifying:

f(2) = {{{(2^2+5)/(4^2-3)}}}

f(2) = {{{(4+5)/(16-3)}}}

f(2) = {{{9/13}}}

Now we need to find {{{(2*f(2))/3}}}.

So we substitute {{{9/13}}} for the f(2) in

{{{(2*f(2))/3}}}.

{{{(2*(9/13))/3}}}.

{{{(18/13)/3}}}.

{{{18/13}}}÷{{{3}}}

{{{18/13}}}·{{{1/3}}}

{{{6/13}}}
