Math Problem Statement

What do you understand by, write down power set of each of the following sets {0,1,2,3,4,5, 6, 7}

Solution

A power set of a given set is the set of all possible subsets of that set, including the empty set and the set itself.

For the set {0,1,2,3,4,5,6,7}\{0, 1, 2, 3, 4, 5, 6, 7\}, the power set contains every possible combination of the elements of the set. If the original set has nn elements, then its power set will contain 2n2^n subsets. Since the given set has 8 elements, the power set will contain 28=2562^8 = 256 subsets.

Here's a brief description of what the power set would look like for {0,1,2,3,4,5,6,7}\{0, 1, 2, 3, 4, 5, 6, 7\}:

  1. Empty set: \emptyset or {}\{\}
  2. Single-element subsets: {0},{1},{2},{3},{4},{5},{6},{7}\{0\}, \{1\}, \{2\}, \{3\}, \{4\}, \{5\}, \{6\}, \{7\}
  3. Two-element subsets: {0,1},{0,2},{0,3},,{6,7}\{0, 1\}, \{0, 2\}, \{0, 3\}, \ldots, \{6, 7\}
  4. Three-element subsets: {0,1,2},{0,1,3},,{5,6,7}\{0, 1, 2\}, \{0, 1, 3\}, \ldots, \{5, 6, 7\}
  5. All the way up to eight-element subset, which is the set itself: {0,1,2,3,4,5,6,7}\{0, 1, 2, 3, 4, 5, 6, 7\}

However, listing all 256 subsets would take up a lot of space, so the important thing to remember is the principle: the power set includes all possible combinations of elements from the original set.


Would you like a more detailed explanation or have any specific questions about this concept?

Here are five related questions for practice:

  1. What is the power set of {a,b,c}\{a, b, c\}?
  2. How many subsets are there in the power set of a set with 5 elements?
  3. What is the formula for the number of subsets in a power set?
  4. Does the power set of a set always include the empty set?
  5. What is the largest subset in a power set?

Tip: The size of the power set grows exponentially with the number of elements in the original set!
