Question

If C = {integers divisible by 2 from 1 to 12} and D = {integers divisible by 4 from 1 to 16}, what is C ∩ D?

Answer 1

C = {2,4,6,8,10}
D = { 4,8,12}
then C ∩ D = { 4,8}
ok?

Answer 2

I'm not following . :(
I don't understand how you got that .

Answer 3

do you understand this:
C = {2,4,6,8,10}

Answer 4

Yeah they're all even integers ..

Answer 5

and do you understand this:
D = { 4,8,12}

Answer 6

Kind of .

Answer 7

Answer 9

ok,4,8,12 are from 1 to 16.OK?did you understand?

Answer 10

Yes ..

Answer 11

and 4,8,12 are divisible by 4,OK?

Answer 12

Following ..

Answer 13

4x1=4
4x2=8
4x3=12
OK?

Answer 14

Yeah ..

Answer 15

so D={4,8,12} and C={2,4,6,8,10}
any problem?

Answer 16

No , i got it .. Thank you . (:

Answer 17

your welcome :) ;)
