send me how to solve this question​

Answer 1

Answer:

52

Step-by-step explanation:

a^3 - b^3 = (a - b)(a^2 + ab + b^2). ---->1

given a - b = 4

eqn 1 can be written as

4[(a +b)^2 - ab)] = 208

(a +b)^2 - ab) = 208/4

(a +b)^2 - ab) = 52.....

Answer 2

Answer:

Option(1)

Step-by-step explanation:

a³ - b³ = 208 and a - b = 4.

Formula is, a³ - b³ = (a-b)(a^2 +ab+b^2)

=> 208 = 4*(a² + ab + b²)

=> 208/4 = (a^2 + ab + b^2)

=> 52 = (a^2 + ab + b^2)

=> 52 = (a + b)^2
