Question

If x4+1/x4 =119 then find x+1/x=

Answer 1

Answer:

473

Step-by-step explanation:

According to question;

$\frac{4x +1}{4x} = 119$  is given

We have to find out the value of $\frac{x+1}{x} = ?$

Let us first find out the value of x;

∵ $4x + 1 = 476 \times x$

$\frac{4x + 1}{4x} = 119$

$1 = 472 \times x$

$x = \frac{1}{472}$

Now , to find out the value of $\frac{x+1}{x}$

$\frac{x+1}{x} = \frac{1/472+1}{1/472}$

= $\frac{473/472}{1/472}$

$\frac{473}{472} \times 472$

∴ 473
