1) If x > y

2) If x >= y

3) If x < y

4) If x <= y

5) If x = y or the relationship can't be established.

1. 

I. √x - √8/√x = 0

II. y^3 – (8)^3/2 = 0

2. 

I. √(x + 7) = √144 - √49

II. y^2 + 188 = 512

3. 

I. 4x – 2y = 10

II. x – y = 3

4. 

I. y^3 – 500 = 1228

II. x^2 – 500 = –211

5. I. y^2 – 15y + 56 = 0

II. x^2 + 10x + 21 = 0
