If $x+\frac{1}{x}= 2$, then the value of $x^{57}+\frac{1}{x^{57}}$
Answer & explanation
Correct answer: option 4
If $x+\frac{1}{x}= 2$
Then put x = 1
$x^{57}+\frac{1}{x^{57}}$ = $1^{57}+\frac{1}{1^{57}}$ = 2
If $x+\frac{1}{x}= 2$, then the value of $x^{57}+\frac{1}{x^{57}}$
Correct answer: option 4
If $x+\frac{1}{x}= 2$
Then put x = 1
$x^{57}+\frac{1}{x^{57}}$ = $1^{57}+\frac{1}{1^{57}}$ = 2
