Answer:
True.
Explanation:
These are sets containing the same exact elements so they are the same set of elements.
They both contain 4 elements.
The 4 elements in each are c, f , j , and k.
It matters not of the arrangement. It also doesn't matter if they repeat an element.
For example these sets are also the same:
{a,a,b} and {a,b}.
They both contain 2 elements and those elements are a and b.
People don't normally write something like {a,a,b} because it is redundant (because of the repetition of a).
Here is an example of some sets that are equal:
{1,2,3}={1,3,2}={2,1,3}={2,3,1}={3,1,2}={3,2,1}.
These are all the same because they all contain the elements: 1 , 2 , and 3. It doesn't matter the order in a set.
