Question 30416
i am not sure what you what to find or prove here.


What i can find for you is the value of k


{{{ log(x, k) * log(5, x)  = 5/2 }}}
{{{ (log(5, k)/log(5, x)) * log(5, x)  = 5/2 }}}
{{{ log(5, k)  = 5/2 }}}
{{{ k = 5^(5/2) }}}
{{{ k = (sqrt(5))^5 }}}
{{{ k = sqrt(5)*sqrt(5)*sqrt(5)*sqrt(5)*sqrt(5) }}}
{{{ k = 5*5*sqrt(5) }}}
{{{ k = 25sqrt(5) }}}
