If the square of X minus 13X plus 1 equals 0, then what is the fourth power of X plus the fourth power of X

If the square of X minus 13X plus 1 equals 0, then what is the fourth power of X plus the fourth power of X

X^2-13x+1=0.x=0.
X-13+1/x=0,
X+1/x=13.
(X+1/x)^2=169
X^2+1/x^2=169-2=167
(X^2+1/x^2)^2=167^2.
X^4+1/^4=167^2-2.
X^4+1/x^4=27887.

Given that the quadratic of |a-1(b+2) is equal to 0, find the value of (a+b) to the power of 2013.

| A-1(b+2)2=0, then:
A-1=0 and b+2=0
Get: a=1, b=-2
Then: a+b=-1
Therefore,2013 power of (a+b)=2013 power of (-1)=-1
