Answer 1

try it

Answer 2

i did ... im getting no answer

Answer 3

first statement says x and y are "relatively prime"

Answer 4

like say 5 and 7

the greatest common divisor of 10 and 21 is 1
no question about it right?

Answer 8

yea

Answer 9

finito

Answer 10

huh?

Answer 11

it means if gcd(x,y) =1
