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.
The smallest Mersenne number is 2.
The 7th Mersenne prime is equal to 2^19-1
1992 is not a Mersenne prime. 1992 is a composite number, being a multiple of 2.
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.
1 is not a Mersenne prime because 21 - 1 = 2 - 1 = 1 and 1 is not a prime number.
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.
2 is the lowest Mersenne prime.
Is basically doubling the number. For example 2 to the second power is 4.
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.
-3^2 = 9 -(3^2) = -9
The first four Mersenne primes are 2, 3, 5, and 7.
199 is not a Mersenne prime because it does not fit the algorithm 2n - 1. 2199 - 1 = does not produce a prime number. The Mersenne primes below 200 are 2, 3, 5, 7, 13, 17, 19, 31, 61, 89, 107, and 127.
