Question

plzzzzzzzzzzzzzzzzz solve

Answer 1

Let’s find x⁴x4 first.
(3+√2)⁴=3⁴+4(3³)(√2)+6(3²)(√2²)+4(3)(√2³)+√2⁴

81+108√2+108+24√2+4

193+132√2
Therefore

x⁴+1/x⁴=193+132√2+1/193+132√2


Now, I’m guessing you want the denominator rationalized and/or over one common denominator. I will do both of them.

First, rationalizing the denominator

1/x⁴=1/193+132√2



=193−132√2/2401


That means that 
x⁴+1/x⁴=193+132√2+193−132√2/2401



Putting it all over one denominator:


x⁴+1/x⁴= 463586+316800√2/2401
