Consider the set a = {a, (b), c). what is the power set of a? o{0, {a}, {a,{b}}, {{b}}, {c, a}, {{b},c}, {c}, {a,{b},c}} o{0, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b,c}} o{0, {a}, {a,{b}}, {{b}}, {a, b,c}, {{b},c}, {c}, {a,{b},c}} o{0, a, b, c, {a, b}, {a, c}, {b, c}, {a, b,c}}

O{{}, {a}, {{b}}, {c}, {a,{b}}, {a,c}, {{b},c}, {a,{b},c}}.

Step-by-step explanation:

You have the following set:

A = {a, {b},c}

The power set of any set A is the set that contains all the subsets of A.

Each set B is a subset of A if B is contained in A.

Each N-cardinality set will have a -cardinality power set.

The subsets of A are:

- The empty set(The empty set is a subset of any set)

- Each element of A. So {a}, {{b}}, {c} are all subsets of A.

- Every combination between elements of A are subsets of A. So {a,{b}}, {a,c}, {{b},c} and {a,{b},c} are all subsets of A.

So the power set of A is

O{{}, {a}, {{b}}, {c}, {a,{b}}, {a,c}, {{b},c}, {a,{b},c}}.

i know the answer is 3

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
