((x^4+2)^(x^4+2))/((x^2+4)^(x^2+4))=1
I have currently found (x^4+2)^(x^4+2)=(x^2+4)^(x^2+4)
Any help further?
This will be true if x4 + 2 = x2 + 4 or x4 - x2 - 2 = 0 or (x2 + 1)(x2 - 2) = 0
The only option that gives real solutions for x is x2 = 2 or x = ±√2
.
Thanks for your help............It was 2^(1/2)
ok so you worked it out yourself and don't want anyone to look at it?
