### Finite Field Extension

How can one recover the coefficients of the polynomial
representation of a number field element when the
number field is not prime?

In the following example,

`F = `~~GF(P)
~~GF(p)
R.<x> = F[]
K.<t> = GF(p^2, ~~modulus = x^2 ~~modulus=x^2 + 1)
a = ~~K.random_element() // ~~K.random_element()

say ~~a = ~~the value of `a`

obtained is

`364*t + 214`

.

How can I read from ~~sage ~~Sage the integer values

`(364, `~~214) , ~~214)

,
I need them for manipulation, I do not want the ~~'t' ~~`t`

there.

please urgent help!!! I am newby to SAGE
