Question 358577
{{{ (sqrt(7)+sqrt(5))/(sqrt(5)+sqrt(2)) =(sqrt(7)+sqrt(5))/(sqrt(5)+sqrt(2))* (sqrt(5)-sqrt(2))/(sqrt(5)-sqrt(2))  }}}
{{{ (sqrt(7)+sqrt(5))/(sqrt(5)+sqrt(2)) =(sqrt(35)-sqrt(14)+5-sqrt(10))/(5-sqrt(10)+sqrt(10)-2) }}}
{{{ (sqrt(7)+sqrt(5))/(sqrt(5)+sqrt(2)) =highlight((sqrt(35)-sqrt(14)+5-sqrt(10))/(3)) }}}
