Question

if x-1/4=3find the value of x4+1/x4​

Answer 1

Answer:

111.575...

Step-by-step explanation:

$\\x-\frac{1}{4} = 3\\x = 3 + \frac{1}{4}\\x = \frac{12+1}{4} \\x = \frac{13}{4}$

$x^{4} + \frac{1}{x^{4} } = (\frac{13}{4})^{4} + \frac{1}{(\frac{13}{4} )^{4} }$

28561/256 + 1/(28561/256)

28561/256 + 256/28561

815796257/7311616

111.575...
