Question 814834
{{{ sqrt( 5/9 ) + sqrt( 5/81) }}}
{{{ sqrt( 5)/sqrt(9 ) + sqrt( 5)/sqrt(81) }}}
{{{ sqrt( 5)/3 + sqrt( 5)/9 }}}
{{{ (sqrt( 5)/3)(3/3) + sqrt( 5)/9 }}}
{{{ (3sqrt( 5))/9 + sqrt( 5)/9 }}}
{{{ (3sqrt( 5)+ sqrt( 5))/9 }}}
Exactly like 3x + x = 4x, the numerator adds to:
{{{ (4sqrt( 5))/9 }}}
