Check if the Galois group of x^4-2 is Z2xZ2, not D8 over Q..Thanks

Sir please upload this : prove that the field extension Q(√5+i) over Q is an algebraic extension

This is quite good. However, because gcd(4, 2) is not 1, who do you conclude that the stacked extensions degree is the product of the individual degrees?

Sir if we want to find fixed field from the all proper subgroups of G then
How can we pricisely write all fixed fields
Is are you teach ?
