Answer 2

Answer:

The correct answer to the given problem is 2.

Step-by-step explanation:

This can be solved by utilising the formula of the given expression-

The formula for evaluating a^3 + b^3 is (a+b)^3 - 3ab( a+b)

Now considering x to be a and 1/x to be b, we get:

So, x^3 + 1/x^3 = 2^3 - 3(2) = 8-6 = 2.
