Answer: a^3 + 1/a^3 + 3(a + 1/a) = b^3.
Step-by-step Explanation:
We all know that (a + b)^3 = a^3 + b^3 + 3ab(a + b). Now, it is given in the question that (a + 1/a) = b.
We can rewrite a^3 + 1/a^3 + 3(a + 1/a) as (a)^3 + (1/a)^3 + 3(a)(1/a)(a + 1/a). Clearly, the expression is the expansion of (a + 1/a)^3.
So, (a + 1/a)^3 = b^3.
