First number = (a + b) (a - b)3
Second number = (a + b)3 (a - b)
Formula used:
Mean proportional = √(Product of numbers)
Calculation:
Mean proportional = √{(a + b) × (a - b)3} × {(a + b)3 × (a - b)}
⇒ √{(a + b) × (a - b)2 ×(a - b) × (a + b)2 ×(a + b) × (a - b)}
⇒ √{(a - b)4 × (a + b)4}
⇒ (a - b)2 × (a + b)2
∴ The correct option is 1.
