(2sqrt10+4)/3210+43

Explanation:

sqrt8/(sqrt 5-sqrt 2)852

:.(sqrt 5+sqrt 2)/(sqrt 5+sqrt 2)=1

:.=sqrt8/(sqrt 5-sqrt 2)xx (sqrt 5+sqrt 2)/(sqrt 5+sqrt 2)

(sqrt8(sqrt5+sqrt2))/((sqrt5-sqrt2)(sqrt5+sqrt2))

:.=(sqrt 8(sqrt 5+sqrt 2))/3

:.=(sqrt 8 sqrt 5+sqrt 8 sqrt 2)/3

:.=(sqrt(8*5)+sqrt(8*2))/3

:.=(sqrt 40+sqrt 16)/3

:.=(sqrt(2*2*2*5)+sqrt 16)/3

:.=sqrt2*sqrt2=2

:.=(sqrt(2*2*2*5)+4)/3

:.=(2 sqrt (2*5)+4)/3

:.=(2 sqrt10+4)/3
