(√8+2)/4. Since, (1/√8-2)*(√8+2/ √8+2)= (√8+2)/(8-4)= (√8+2)/4

hey
explain 1 n 2nd step
please
(a+b) (a-b)= a2 -b2 (this is a to the power 2 and b to the power 2)
so when you use this formula and multiply an irrational number with itself it will become rational. For example { (a)1/2- b} (a to the power half) when multiplied by {(a)1/2 + b} it becomes {a- (b)2} (b square)
