If Y = {x | x is a positive factor of the number 2p – 1 (2p – 1),

1.	If Y = {x \| x is a positive factor of the number 2p – 1 (2p – 1), where 2p – 1 is a prime number}.Write Y in the roaster form.
Answer» Y = {x \| x is a positive factor of the number 2^{p – 1} (2^p – 1), where 2^p – 1 is a prime number}. Y- {x \| x is a positive factor of the number 2^p-1 (2^p – 1), where 2^p – 1 is a prime number}. So, the factors of 2p-1 are 1,2,2²,2³ ,…, 2^p-1 . Y= {1,2,2² ,2³ , …,2^p-1 ,2^p -1}

If Y = {x | x is a positive factor of the number 2p – 1 (2p – 1), where 2p – 1 is a prime number}.Write Y in the roaster form.

Answer»

Y = {x | x is a positive factor of the number 2^{p – 1} (2^p – 1), where 2^p – 1 is a prime number}.

Y- {x | x is a positive factor of the number 2^p-1 (2^p – 1), where 2^p – 1 is a prime number}.

So, the factors of 2p-1 are 1,2,2²,2³ ,…, 2^p-1 .

Y= {1,2,2² ,2³ , …,2^p-1 ,2^p -1}
