    Can the GCD of Polynomials in a Field Always Be Reduced to 1?

    Homework Statement We know that the gcd of two polynomials can be written as gcd(p(x),q(x))=p(x)m(x) + q(x)n(x) for some n(x) and m(x) in F[x] F a fieldI want to show gcd(n(x),m(x))=1 for a fixed gcd(p(x),q(x)) The Attempt at a Solution Well, what I tried was to let D(x)=gcd(p(x),q(x))...

    Number Theory: Divisibility and Prime Factorization

    {SOLVED}Number theory/ divisibility Show that m^2 is divisible by 3 if and only if m is divisible by 3. MY attempt: I assumed that 3k=m for some integers k and m. squared both sides and now get. 3n=m where n=3*(3k^2). Thus 3|m^2 Now the problem is when i assume: 3k=m^2 and need...

    Prove the formula of squareroot 2

    Thanks for helping! I solved it by using the fact that (1-1/50)^(-1/2)=squareroot(50/49)=1+1/(2*50) + 1*3/(2*4*5*50^2)+1*3*5/(1*2*3*50^3) Then 5*squareroot(2)/7=(1+1/100+1*3/(100*200)+1*3*5/(100*200*300))

    Prove the formula of squareroot 2

    [SOLVED] prove the formula of squareroot 2 Verify the following formula: Squareroot (2)=7/5*(1+ 1/100 + 1*3/(100*200) + 1*3*5/(100*200*300) + etc..) Use the Fact that 50=5^2*2=7^2+1 Theorem: (1+x)^a=1 +a*x/1 + (a(a-1)*x^2)/(1*2)+ (a(a-1)(a-2)*x^3)/(1*2*3)+ etc... Hint: use the...
