Answer:

x³ +1/x³=??????????????????????/

Step-by-step explanation:

Answer 2

Answer:

I think you've missed the specific value for x^3+1/x^3 that might be given in the question

If, x^3+1/x^3 = a

We know that,

(x+1/x)^3 = x^3+1/x^3 + 3(x+1/x)

Let, x+1/x = u

So,

u^3 = a + 3u

or,

u^3 - 3u - a = 0

Now, If we can calculate the root of this equation, then we have got the value of x+1/x

Hope this helps you !
