Step-by-step explanation:
GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.
Answer:
{∅, {a}, {b}, {a,b}}
Step-by-step explanation:
The value of power of a set is generalized by using the formula,
Power of a set (P) = 2^n where n is the number of element in the set.
Given two distinct elements a and b say;
A = {a,b}
n(A) = 2 i.e the number of elements in the set is 2. Therefore the power of the set will be 2^n which gives 2^2 = 4.
P(A) = 4 means there are 4 subsets of the given set. Subsets are sets of elements that can be found in the set. The subsets of element A will be;
{∅, {a}, {b}, {a,b}} which gives 4 elements in total.
Note that empty set ∅ is always part of the subset of any given set
