Three proportions: (a4 - b4), (a2 - ab), (a2 + b2)
Concept:
The fourth proportional of three numbers x, y, and z is (y × z)/x.
Solution:
⇒ Fourth proportional = (a2 - ab) × (a2 + b2)/(a4 - b4)
⇒ Fourth proportional = a/a + b
Therefore, the fourth proportional of (a4 - b4), (a2 - ab), and (a2 + b2) is a/(a + b).
