Question

(a^3+3ab^2) /(a^3+3ba^2)=63/62​

Answer 1

Step-by-step explanation:

We have

a3 + 3ab2/b3 + 3a2b = 63/62

App. Componendo and Dividendo

a3 + 3ab2 + b3 + 3a2b/ a3 + 3ab2 - b3 - 3a2b = 63 + 62/63 – 62

a3 + b3 + 3ab2 + 3a2b/a3 + 3ab2 - b3 - 3a2b = 125/1

(a + b)3/(a – b)3 = 125/1

a + b/a – b = 5/1

Again Applying Componendo and Dividendo

a + b + a – b/a + b – a + b = 5 + 1/5 – 1

2a/2b = 6/4

a : b = 3 : 2

Answer 2

Answer:

the answer is a²+b²+c²=(a+b)²
