Question

if (x+1/x) -10, the value of (x²+1/x²) will be​

Answer 1

Answer:

98.

Step-by-step explanation:

Given that,   $x+\frac{1}{x}=10$

               => $x^{2}+\frac{1}{x^{2}} +2(x)(\frac{1}{x} )=100$     [squaring on both sides]

               => $x^{2}+\frac{1}{x^{2}}+2 = 100$

               => $x^{2}+\frac{1}{x^{2}} = 98$
