Question

Перечислите элементы каждого из множеств A и B: A = { x | x -натуральное , -2 < x < 8 }, B = { x | x - целое , x-3=7}.

Answer 1

A={x|x∈N, -2<x<8}
A={1;2;3;4;5;6;7}

B={x|x∈Z, x-3=7}
x-3=7
x=7+3
x=10
B={10}

Answer 2

Elements of Set A:

Set A is defined as A = {x | x is a natural number, -2 < x < 8}. This means that the elements of set A are natural numbers between -2 and 8, excluding -2 and 8.

The elements of set A are: {0, 1, 2, 3, 4, 5, 6, 7}.

Elements of Set B:

Set B is defined as B = {x | x is an integer, x - 3 = 7}. This means that the elements of set B are integers that satisfy the equation x - 3 = 7.

Solving the equation x - 3 = 7, we find that x = 10.

Therefore, the only element of set B is: {10}.

To summarize: - Elements of set A: {0, 1, 2, 3, 4, 5, 6, 7}. - Elements of set B: {10}.
