Complex numbers

Simplify the complex numbers in term of i. z= (1+3i)/(1-4i)

Let E be an extension field of a finite field F, where F has q elements....

Let E be an extension field of a finite field F, where F has q elements. Let a in E be an element which is algebraic over F with degree n. Show that F(a) has q^n elements. Please provide an unique answer and motivate all steps carefully. I also prefer that the solution is provided as written notes.

Problem 3. Let F ⊆ E be a field extension. (i) Suppose α ∈ E is algebraic of odd degree over F. Prove that F(α) = F(α^2 ). Hints: look at the tower of extensions F ⊆ F(α^2 ) ⊆ F(α) and their degrees. (ii) Let S be a (possibly infinite) subset of E. Assume that every element of S is algebraic over F. Prove that F(S) = F[S]

Theorem: Let K/F be a field extension and let a ∈ K be algebraic over F....

Theorem: Let K/F be a field extension and let a ∈ K be algebraic over F. If deg(mF,a(x)) = n, then 1. F[a] = F(a). 2. [F(a) : F] = n, and 3. {1, a, a2 , ..., an−1} is a basis for F(a).

(a) look at these the complex numbers z1 = − √ 3 + i and z2 = 3cis(π/4). write the following complex numbers in polar form, writing your answers in principal argument: i. z1 ii. z1/|z1|. Additionally, convert only this answer into Cartesian form. iii. z1z2 iv. z2/z1 v. (z1) -3 vi. All complex numbers w that satisfy w 3 = z1. (b) On an Argand diagram, sketch the subset S of the complex plane defined by S = {z...

The medical field often is an extremely complex and confusing industry with not a lot of information available in terms that can easily be understood. Give your personal perspective regarding the quality of patient education you or a family member received in the past. Provide a brief summary of the education that you received including who was the medical leader responsible for communicating with you or your family member. Who were the other members of the healthcare team and how...
