Question

Write the following sets in roster form 1) B = {x : x is a positive factor of a prime number} 2) C={x : x2=x where x belongs to Real numbers}

Answer 1

Step-by-step explanation:

Given,

1. B = {x: x is a positive factor of a prime number}

=> B = {1}

Since 1 is the only posotive factor of a prime number.

2. C = {x: $x^{2}$ = x where x belongs to Real numbers}

=> C = {0, 1}

Since, $0^{2}$ = 0×0 = 0

and $1^{2}$ = 1×1 = 1

Answer 2

Step-by-step explanation:

Given,

1. B = {x: x is a positive factor of a prime number}

=> B = {1}

Since 1 is the only posotive factor of a prime number.

= x where x belongs to Real numbers}

=> C = {0, 1}

Since,

0^{2}

= 0×0 = 0

and

1^{2}

= 1×1 = 1
