Question

If + 1/x = 3 ,find the value of x^4 + 1/x^4





​

Answer 1

Answer:

81.01

Step-by-step explanation:

1/x = 3

x = 1/3

x^4+1/x^4 = (1/3)^4 + 3^4

= 1/81 + 81

= (1+6561)/81

= 6562/81

= 81.01

Answer 2

Answer:

81.012

Step-by-step explanation:

1/x=3

or, x= 1/3

Then,

x⁴ + (1/x)⁴

= (1/3)⁴+ (3)⁴

= 1/81 + 81

= 6562/81

= 81.012
