Assume
 \sqrt{(7 + 2 \sqrt{5} }  = x
squaring
 {x}^{2}  = 7 + 2 \sqrt{5}
then
 {x}^{2}  - 7 = 2 \sqrt{5}
again squaring,

RohNav: i left my answer not answered well you will square the given equation again. you'll get a bi-quadratic equation in x which you can by substitution convert into a quadratic equation and solve from there.
RohNav: hope it helps
