 Express as a single logarithm.
40 log5 5 square root of x + log5(40x6) - log5 40 
{{{40log(5,sqrt(x))+ log(5,40x^6) - log(5,40)}}}
deal with the first term
{{{40log(5,sqrt(x))}}} = {{{log(5,(x^(1/2))^40)}}} = {{{log(5,x^20)}}}
now we have
{{{log(5,x^20)+log(5,40*x^6)-log(5,40)}}}
plus is multipy, minus is divide
{{{log(5,(x^20*40*x^6)/40)}}}
40 cancels, add the exponents of the like terms x
{{{log(5,x^26)}}}</PRE>
