Answer 2

Answer:

Answer is 35/8.

Step-by-step explanation:

Given,,

a/b = 3/2.

; a = 3x b = 2x.

Let's find the value of a^3+b^3/b^3.

as we know that,,

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

Now,,

(3x + 2x)[(3x)^2 - (3x)(2x) + (2x)^2]/(2x)^3

; 5x(9x^2 - 6x^2 + 4x^2)/8x^3

; 5x(7x^2)/8x^3.

; 35x^3/8x^3.

; 35/8.
