Q
Q: If F = {1, 2, 3}, what is the number of elements in the power set of F?
Solution:
The power set of a set with n elements has 2^n elements. For F, n = 3, so the power set has 2^3 = 8 elements.
Steps: 6
Show Steps
Step 1: Identify the set F. In this case, F = {1, 2, 3}.
Step 2: Count the number of elements in the set F. There are 3 elements: 1, 2, and 3.
Step 3: Use the formula for the power set. The power set of a set with n elements has 2^n elements.
Step 4: Substitute the number of elements (n = 3) into the formula. So, we calculate 2^3.
Step 5: Calculate 2^3, which equals 8.
Step 6: Conclude that the power set of F has 8 elements.
