Answer 1

Answer:

if x = 2 + root 3 find value of x^3 +1/x^

Step-by-step explanation:

solve the problem yourself this is very easy

Answer 2

Answer: 52

Step-by-step explanation:

We have ,

x=2+√3 therefore by rationalizing , we get

1/x=2-√3

and x+1/x=2+√3+(2-√3)

we get x+1/x=4

By cubing both sides

• (x+1/x)^3= 4^3=64
• x^3+(1/x)^3+3x(1/x){x+1/x}=64
• x^3+(1/x)^3+3(4)=64
• x^3+(1/x)^3=64-12
• x^3+1/x^3=52

hence we got the answer
