Question 835135
{{{(3^3+sqrt(5))/(3^1+sqrt(5)) =(27+sqrt(5))/(3+sqrt(5))}}}
{{{(3^3+sqrt(5))/(3^1+sqrt(5)) =((27+sqrt(5))/(3+sqrt(5)))*((3-sqrt(5))/(3-sqrt(5)))}}}
{{{(3^3+sqrt(5))/(3^1+sqrt(5)) =((81-27*sqrt(5)+3*sqrt(5)-5)/(9-3*sqrt(5)+3*sqrt(5)-5))}}}
{{{(3^3+sqrt(5))/(3^1+sqrt(5)) =(76-24*sqrt(5))/(4))}}}
{{{(3^3+sqrt(5))/(3^1+sqrt(5)) =19-6*sqrt(5)}}}
