Answer 2

PROPER QUESTION:-

if the value of x is 18 ,then find the value of $x^{2}+\frac{1}{x^2}}$

FINAL ANSWER:-

$=\frac{104977}{324}\:\:\:\:or\:\:\:\:324$

GIVEN:-

$x=18\\x^{2}+\frac{1}{x^2}}$

TO FIND:-

value of  $x^{2}+\frac{1}{x^2}}$

SOLUTION:-

x=18

$=18^{2}+\frac{1}{18^2}}\\=324+\frac{1}{324}\\=\frac{324*324+1*1}{324}\\=\frac{104976+1}{324}\\=\frac{104977}{324}\:\:\:\:or\:\:\:\:324$
