a = 61 and b = 26

Find all pairs of Bezout coefficients for a and b

If the gcd of the two numbers is 1 also find an inverse of the small number modulo the big number.

Answer #1

Suppose that A=[xy67]A=[x6y7] and B=[x0xy]B=[xx0y], for some
real numbers xx and yy. Find all ordered pairs (x,y)(x,y) such that
AB=BA AB=BA.

Find the GCD d(x) of the following pairs of polynomials
a(x),b(x) in Z3[x]. In each case,
express d(x) as a linear combination of a(x) and b(x).
a) a(x)= x3 + x2 +1 , b(x)=
x2+1
b) a(x)= x3 + x2+ 1 , b(x)= x2
+ x + 1
c) a(x)= x3 +x2 +1 ,b(x)= x2 +

8. List all irreducible polynomials with binary coefficients of
degree 4 or less. (Hint: produce a times table that shows the
minimum number of products needed.) Show these as binary numbers
(omitting the indeterminant) and as decimal numbers (interpreting
the binary number into decimal). Is 23 a prime polynomial in this
field?
9. Interpreting these decimal numbers into coefficients of
polynomials with binary coefficients, what is the product of 11 and
10 modulo 31 in GF(2^4) over P = 31?...

Let V be the set of all ordered pairs of real numbers. Consider
the following addition and scalar multiplication operations V. Let
u = (u1, u2) and v = (v1, v2).
• u ⊕ v = (u1 + v1 + 1, u2 + v2 + )
• ku = (ku1 + k − 1, ku2 + k − 1)
1)Show that the zero vector is 0 = (−1, −1).
2)Find the additive inverse −u for u = (u1, u2). Note:...

A local police chief claims that 61%61% of all drug-related
arrests are never prosecuted. A sample of 700700 arrests shows that
58%58% of the arrests were not prosecuted. Using this information,
one officer wants to test the claim that the number of arrests that
are never prosecuted is less than what the chief stated. Is there
enough evidence at the 0.020.02 level to support the officer's
claim?
Step 1 of 7 :
State the null and alternative hypotheses.
step 2...
