Let A = {-6, -12⁄4, -5⁄8, -√3, 0, ¼, 1, 2π, 3, √12}. List all the elements of A that belong to each set. Integers

Guida verificata passo dopo passo

First, recall the definition of integers: integers are whole numbers that can be positive, negative, or zero, but they do not include fractions or irrational numbers.

Next, examine each element of the set \(A = \{-6, -\frac{12}{4}, -\frac{5}{8}, -\sqrt{3}, 0, \frac{1}{4}, 1, 2\pi, 3, \sqrt{12}\}\) to determine if it is an integer.

Simplify any elements that are fractions or radicals to see if they reduce to integers. For example, simplify \(-\frac{12}{4}\) and \(\sqrt{12}\).

Check if the simplified values are whole numbers without fractional or decimal parts. If yes, include them in the list of integers.

Finally, list all elements from \(A\) that meet the integer criteria based on your analysis.
