Question

if x^+1/x^=51 find value of (x-1/x)

Answer 1

=>x^2+1/X^2= (x-1/x)^2+2.x.1/x
=>51-2=(x-1/x)^2
=>root49=x-1/x
=>x-1/x=7.


Hope it helps you....

Answer 2

Answer:

Hello mate your ans..will be 7

Step-by-step explanation:

(x²-$\frac{1}{x}^{2}$)²

=x²+$\frac{1}{x}^{2}$-2×$x$×$\frac{1}{x}^{2}$

=x²+$\frac{1}{x}^{2}$-2 =51

=x²+$\frac{1}{x}^{2}$=51-2

=x²+$\frac{1}{x}^{2}$=49

=(x-$\frac{1}{x}$)²=49

=x-$\frac{1}{x}$=$\sqrt{49}$

=x-$\frac{1}{x}$=7
