ONLINE CLASS OF MATHEMATICS FOR
VIII CLASS
TEACHER : SIR AHSAN
TOPIC : SET
Our first topic in set was power set
The formula of Power set is:
P = 2n
Where,
P = power set
2 = constant (never change)
N = total number or elements given in a set.
Q1: List the members of the power set of the
following sets:
V) {a, b, c, d}
solution:
Using formula,
P = 2n
P = 24
P = 2x2x2x2
P = 16 sets
 {}, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c},
{b,d}, {c,d}, {a,b,c}, {a,b,d}, {a,c,d}, {b,c,d},
{a,b,c,d}
