Question

if x-1/x=7 then evaluate:x^2+1/×^2​

Answer 1

Given, x-1/x=7

x²+1/x² = ?

Now, x²+1/x² = (x-1/x)²+2.x.1/x

= 7²+2

= 49+2 = 51 Answer.

Answer 2

Answer:

9477

Step-by-step explanation:

${5232}^{26} \div \frac{441}{93 = \div 3264} \times 63$

$\sqrt[52.22]{?0...262ifb} ghd \cos(e \sec(6222) ) ) 52 \times \frac{223}{?} \\ x \frac{x}{?} = 942 \times {52}^{2} \times 2.. \times \frac{8}{2}$
