Question

Write the given set in roster form: D = {x : x is a prime number which is divisor of 60}

Answer 1

as you know, there are two method to represent a set.
(1) set builder form (2) roaster form or tabular form.
roaster form or tabular form :- in roaster form, all the elements of the set are listed, elements are being separated by commas and are enclosed within curly brackets { }.
for example :- A is set of all natural numbers
then we can write A in roaster from like as A = {1,2,3,4,..... }

here, D = {x : x is a prime number which is divisor of 60}
divisor of 60 = 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
but prime numbers are 2, 3, 5
hence, roaster form of D = { 2, 3, 5}

Answer 2

Answer:

D = { 2,3,5 }

Step-by-step explanation:

Given ,

D = { x:x is a prime number

which is divisor of 60 }

Divisors of 60 = { 1,2,3,4,5,6,10,12,

15,20,30,60 }

Now ,

D = { 2 , 3 , 5 }
