The number is 5! = 120
2 power 20
In a skew symmetric matrix of nxn we have n(n-1)/2 arbitrary elements. Number of arbitrary element is equal to the dimension. For proof, use the standard basis.Thus, the answer is 3x2/2=3 .
true
5 expressed as a Roman numeral is V which is symmetrical
The number of arrays (or subsets) that can be formed from a set of 42 elements is determined by the formula (2^n), where (n) is the number of elements in the set. Therefore, for 42 elements, the number of possible arrays is (2^{42}), which equals 4,398,046,511,104. This includes all possible combinations, including the empty set and the full set itself.
2^(n^2+n)/2 is the number of symmetric relations on a set of n elements.
the total no of reflexive relation on an n- element set is 2^(n^2-n).

make a table as I did below for the set {a,b,c} with 3 elements. A table with all n elements will represent all the possible relations on that set of n elements. We can use the table to find all types of relations, transitive, symmetric etc. | a | b | c | --+---+---+---+ a | * | | | b | | * | | c | | | * | The total number of relations is 2^(n^2) because for each a or b we can include or not include it so there are 2 possibilities and there are n^2 elements so 2^(n^2) total relations. A relation is reflexive if contains all pairs of the form {x,x) for any x in the set. So this is the diagonal of your box. THESE ARE FIXED! No, in reflexive relation we still can decide to include or not include any of the other elements. So we have n diagonal elements that are fixed and we subtract that from n^2 so we have 2^(n^2-n) If you do the same thing for symmetric relations you will get 2^(n(n+1)/2). We get this by picking all the squares on the diagonal and all the ones above it too.
It tells you the atomic number, the number of protons, the density, its relations to other elements, and its characteristics.

yes
Yes.
no that's not possible
It depends what you mean by symmetric. If you mean that there are the same number of factors on each branch, then the answer is No. eg 20 / \ 4 5 / \ 2 2
Two primes are symmetric primes of a natural number (n) if their average is n. For example 10, has two pairs of symmetric primes. 7 and 13, and 3 and 17 because their averages are 10.
