Question

Complete the following activity to decide whether
the sets A and B are equal sets or not
A-Set of even prime numbers
B=(x17x-1-13)
Write the sets A and B by listing method
(1)
A-
Por set B
72-1-13
B
- (2)
Prom (1) and (2),
Set A
set B​

Answer 1

A=even prime no.=2

A=2

Set B=x,7x−1=3

7x−1=3→7x=3+1=4

x= 7/4

∴ Set B={ 4/7}

From above we see that set A ≠ set B
