Question

If (a+1/a)^3 = 3,and a≠0,then find the value of (a^3+1/a^3)​

Answer 1

Answer:

3 + 3∛3

Step-by-step explanation:

Notice that (x+y)³ = x³ + 3x²y + 3xy² + y³.

Putting x=a and y=1/a gives

      (a+1/a)³ = (a³ + 1/a³)  +  3(a + 1/a)

⇒  a³ + 1/a³  =  (a+1/a)³ + 3(a+1/a)

                    = 3 + 3∛3
