Best Answer

2 to the power of 2 is NOT the second Mersenne number. The second Mersenne number is 3, derived from the Mersenne algorithm 22 - 1 = 3.

What mersenne primes aren't prime?

Did you mean what Mersenne numbers are prime? If a number is a prime, how is it not a prime at the same time? Anyways, M11, or (2^11) - 1, I think is the lowest Mersenne Number Mp that isn't prime, when p is prime. Any Mersenne Number where p is not prime cannot be prime.

Is 1 a mersenne prime?

1 is not a Mersenne prime because 21 - 1 = 2 - 1 = 1 and 1 is not a prime number.

Why is two a mersenne prime?

Two is a Mersenne prime because it follows the algorithm 2n - 1 to produce the prime number 3 (22 - 1 = 4 -1 = 3).* * * * *Mersenne primes can be defined in two equivalent ways:Numbers of the form 2n - 1 where n is a primeor where the number 2n - 1 is itself a prime.The more commonly accepted definition is the second one. Thus n = 2 gives the smallest Mersenne prime, which is 3.But, since n = 2 gives a result that is prime, it is also sometimes referred to as a Mersenne prime.

What is first Mersenne prime number?

According to Mersenne 2n - 1 is a prime number(where n is also a prime number).As we all know the first prime number is 2 so putting the value of 2 in Mersenne's expression we get 22 - 1 = 3. So, 3 is the first Mersenne prime.Mersenne expression was considered as a method of finding primes. But it didn't always give prime number. Let us consider an example:Putting n = 11 in the expression we get 211 - 1 = 2047, but 2047 is not a prime number.Visit the below related link to know more.
