Question : If $\left(x+\frac{1}{x}\right)=5$, and $x>1$, what is the value of $\left(x^8-\frac{1}{x^8}\right)?$

Option 1: $60605 \sqrt{21}$

Option 2: $60615 \sqrt{21}$

Option 3: $60705 \sqrt{21}$

Option 4: $60725 \sqrt{21}$

Team Careers360 24th Jan, 2024

Correct Answer: $60605 \sqrt{21}$


Solution : Given: $\left(x+\frac{1}{x}\right)=5$--------------(i)
Now, $\left(x^8-\frac{1}{x^8}\right)$
$=(x^4-\frac{1}{x^4})$$(x^4+\frac{1}{x^4})$
$=(x^2-\frac{1}{x^2})$$(x^2+\frac{1}{x^2})$$(x^4+\frac{1}{x^4})$
$= (x-\frac{1}{x})$$(x+\frac{1}{x})$$(x^2+\frac{1}{x^2})$$(x^4+\frac{1}{x^4})$----------(ii)
Squaring equation (i), we get,
$(x+\frac{1}{x})^2 = 5^2$
$⇒(x^2+\frac{1}{x^2}+2) = 25$
$⇒(x^2+\frac{1}{x^2}) = 23$-----------------(iii)
Squaring equation (iii), we get,
$(x^2+\frac{1}{x^2})^2 = 23^2$
$⇒(x^4+\frac{1}{x^4}+2) = 529$
$⇒(x^4+\frac{1}{x^4}) = 527$---------------(iv)
Subtracting 2 on both sides of equation (iii),
