Question

If x+1/x=6 find x^4+1/x^4
​

Answer 1

Answer:

( x + 1 )/x = 6

x + 1 = 6x

x = 1/5

THEN,

               $x^{4}$ + 1 / $x^{4}$ = 626

Answer 2

Answer:

Step-by-step explanation:

x+1/x=6

=>x+1=6x

=>5x=1

=>x=1/5

Now,x^4+1/x^4 = (1/5)^4 + 1 / (1/5)^4 =1+5^4/5^4 * 5^4 = 1+5^4 =1+625=626.
