I was instructed to try .change_ring(IntergerModRing()) for other non finite fields but it is not working. What other commands could I try?JSCHWINGTue, 29 Jun 2021 17:15:25 +0200https://ask.sagemath.org/question/57808/Ideal Radicals Question?https://ask.sagemath.org/question/7990/ideal-radicals-question/
Hello experts,
Given that there is a commutative ring R and 2 ideals I and J, also given that I is included in J
I need to prove
1) radical of I is in radical of J
2) radical of radical of ideal I = radical of ideal I.
Please give me a detailed answer, I need it urgently!!!!
Thanks in advance!SteveSat, 12 Mar 2011 10:07:19 +0100https://ask.sagemath.org/question/7990/Abstract Algebra Questionhttps://ask.sagemath.org/question/7797/abstract-algebra-question/My teacher gave us an extra credit problem using sage, I am having soo much trouble just trying to get started and was hoping for any sort of help possible. Heres the question: An element a in Z mod n is a square if there is some b element of Z mod n such that a^2 = b. Find the number of squares in Z mod p^(n).
Would the code look something like this:
for p^2 = b, let p be prime:
print modulo(Integer(Z):
....
This is my first time ever using a computer program. Sage seems very powerful and I expect to use it more during my school break, but if anyone can help me now, I would greatly appreciate it!!!!!
