Answer:
Step-by-step explanation:
x+1/x = 2
(x+1/x)²=2²
→x²+1/x²+2=4
or x²+1/x²=2
Similarly ( x²+1/x²)³=2³
→ ( x^6+1/x^6)+3(x²)(1/x²)(( x²+1/x²)=8
→ ( x^6+1/x^6)+3× 2=8
( x^6+1/x^6) =2
→( x^6+1/x^6)² =2²
→ x^12+1/x^12+2 =4
and x^12+1/x^12 =2
Similarly
x^24+1/x^24 =2
and x^24+1/x^24 −2=2−2=0
→(x^12−1/x^12)²=0
Hence x^12−1/x^12=0
