Verified answer

I am implying that you mean

8 / {[sqrt(2)] + (1)}

[(8) / {[sqrt(2)] + (1)}] * [{[sqrt(2)] - (1)} / {[sqrt(2)] - (1)}]

8 * {[sqrt(2)] - (1)}

Assuming:8/1+√2

=8/1 + √2 = 8+1.41 = 9.41 <=ANS1 or

assuming:8/1+√2

=8/(1+ √2) = 8/2.41 = 3.32 <=ANS2

-8/1+sqrt2

-8/1= -8. Sqrt2= 1.41....

-8+1.41...

-6.5857...

The answer is 5.414

lolwut?
