Answer 2

[0010001111]... Hello User... [1001010101]
Here's your answer...

a²+b² = 177
ab = 54

(a+b)² = a²+b²+2ab
= 177+2×54
= 177+108
= 285

(a-b)² = a²+b²-2ab
= 177-2×54
= 177-108
= 69

(a+b)/(a-b)
= (285/69)^½
= (95/23)^½

This is a rather odd number. Please tell me whether the question is correct.
