X,Y are polynomials of n, and n is an element of N, then

In summary, X is a set of numbers obtained by raising 4 to the power of a natural number and subtracting 3 times that number and 1, divided by that number. Y is a set of numbers obtained by multiplying 9 with a natural number reduced by 1. XUY is a set that contains X, Y, the set of natural numbers, and an empty set. The exact representation of 4^n-3n-1/ n is not specified and the members of X and Y can vary depending on the value of n. It is recommended to visualize the equations and seek clarification for precise understanding.

First, list some of the members of X and Y.

But does "4^n-3n-1/ n" mean
4^(n- 3n- 1/n)

or 4^(n- 3n- 1)/n

or ((4^n)- 3n- 1)/n

or 4^n- 3n- (1/n)?

Please be precise.

Exactly. List the members of X and Y. Also, try and visualize the equations mentally as what they are describing in words. Apne aap kuchh samajh main aa jayega!

Phir, come back and post here
 

1. What does it mean for a polynomial to be an element of N?

A polynomial being an element of N means that its coefficients and variables are all natural numbers (positive integers). In other words, the polynomial only contains non-negative powers of the variable, and all coefficients are non-negative integers.

2. Can X or Y be any type of polynomial, or do they have to be specific types?

X and Y can be any type of polynomial as long as their coefficients and variables are all natural numbers. This means they can be monomials, binomials, trinomials, or any other type of polynomial as long as they meet the criteria of being an element of N.

3. How is this statement different from saying "X and Y are polynomials of n"?

This statement specifies that n is an element of N, meaning that n must be a natural number. Without this specification, n could potentially be any real number. Additionally, stating that n is an element of N also implies that the coefficients and variables of X and Y must also be natural numbers.

4. Are there any specific properties or rules that apply to polynomials of n?

Polynomials of n have all the same properties and rules as any other polynomial, as long as they meet the criteria of being an element of N. This means they can be added, subtracted, multiplied, and divided (except by 0) just like any other polynomial.

5. Can the statement be rewritten as "If n is a natural number, then X and Y are polynomials of n"?

Yes, the statement can be rewritten in this way. It is essentially saying the same thing, just in a different order. However, the original statement is more commonly used and may be easier to understand for some individuals.
