For a rational number to be absolutely irreducible, what field must it pass through?
Correct Answer
B. Complex field
Explanation
A rational number is said to be absolutely irreducible if it cannot be further reduced or simplified. In order for a rational number to be absolutely irreducible, it must pass through the complex field. The complex field consists of all numbers of the form a + bi, where a and b are real numbers and i is the imaginary unit. This field allows for the representation of all rational numbers, as well as irrational numbers and complex numbers. Therefore, passing through the complex field ensures that a rational number cannot be further simplified or reduced, making it absolutely irreducible.

For field K, how do we describe if the field is irreducible?
Correct Answer
A. Algebraic extension of K
Explanation
An algebraic extension of a field K is a field L that contains K and every element of L is a root of a polynomial with coefficients in K. This means that every element in L can be obtained by performing algebraic operations (addition, subtraction, multiplication, and division) on elements in K. Therefore, if a field K is described as an algebraic extension, it means that all elements in K can be expressed as roots of polynomials with coefficients in K, indicating that K is irreducible.
3.
What is the synonym of an absolutely irreducible algebraic set?
Correct Answer
A. Algebraic variety
Explanation
An absolutely irreducible algebraic set is a set that cannot be expressed as the union of two proper algebraic subsets. An algebraic variety is a geometric object that is defined as the zero set of a collection of polynomial equations. Therefore, an algebraic variety is a synonym for an absolutely irreducible algebraic set.
4.
Which algebraic group is the absolutely irreducible applied to?
Correct Answer
C. Linear representation
Explanation
The correct answer is Linear representation. In mathematics, an algebraic group is said to be absolutely irreducible if it cannot be decomposed into a direct product of nontrivial algebraic subgroups. The linear representation of an algebraic group refers to the group action on a vector space, where the group elements are represented by linear transformations. This representation is often used to study the structure and properties of the algebraic group.
5.
How do we represent the absolutely irreducible of an univariate polynomial of degrees greater or equal to 2?
Correct Answer
D. They have no absolutely irreducible value
Explanation
The correct answer is "They have no absolutely irreducible value." This means that univariate polynomials of degrees greater than or equal to 2 cannot be represented in a way that simplifies or reduces them further. They cannot be factored into simpler forms or expressed in terms of simpler functions. This is in contrast to linear polynomials, which can be represented in a simpler form. Similarly, geometric patterns and polynomial representations do not apply to these higher-degree polynomials.
6.
What do we call the decomposition of a multivariate polynomial as a product of absolutely irreducible polynomials?
Correct Answer
A. Absolute factorization
Explanation
The decomposition of a multivariate polynomial as a product of absolutely irreducible polynomials is called absolute factorization.
7.
How do we represent the absolutely irreducible algorithms?
Correct Answer
B. Polynomials
Explanation
Polynomials can represent absolutely irreducible algorithms because they are mathematical expressions that involve variables and coefficients, and can be used to model and solve various problems. Polynomials can be manipulated using algebraic operations such as addition, subtraction, multiplication, and division, allowing for the creation of complex algorithms. Additionally, polynomials have the property of irreducibility, meaning they cannot be factored into simpler polynomials. This makes them suitable for representing algorithms that cannot be further simplified or broken down into smaller components.
8.
What are absolutely irreducible polynomials also called?
Correct Answer
A. Non-constant polynomials
Explanation
Absolutely irreducible polynomials are non-constant polynomials that cannot be factored into smaller polynomials over a given field. These polynomials are called non-constant because they are not constant polynomials, which are polynomials with a single term. They are also not random polynomials or fractional polynomials, as these terms do not accurately describe the nature of absolutely irreducible polynomials.
9.
What does the property of irreducibility depend on?
Correct Answer
B. Nature of coefficients
Explanation
The property of irreducibility depends on the nature of coefficients. Irreducibility refers to the inability to factorize a polynomial into non-trivial factors. The nature of coefficients, such as whether they are rational or irrational, real or complex, can determine whether a polynomial is irreducible or not. For example, if the coefficients are rational, it is possible to factorize the polynomial using rational roots theorem. On the other hand, if the coefficients are irrational or complex, it may not be possible to factorize the polynomial further, making it irreducible.
10.
What sole condition describes a univariate polynomial that is absolutely irreducible?
Its degree must be...
Correct Answer
D. 1
Explanation
A univariate polynomial is absolutely irreducible if it cannot be factored into polynomials of lower degree with coefficients in the same field. In this case, the correct answer is 1, meaning that the polynomial must have a degree of 1. This means that the polynomial is a linear equation and cannot be factored further.
