An emirp number is a Prime number which, when you reverse the digits, produces a different prime number. Therefore, there are no single-digit emirp numbers.
The first three emirp numbers are:
13, 17, 31
No, it is not.
120
403
product = 6 first three positive counting numbers = 1, 2, 3product of the first three positive counting numbers:1 x 2 x 3 = 6

"emirp" is "prime" spelled backwards. An emirp number is a prime number whose reverse is also a prime. However, palindromic primes are excluded. So 13 / 31 are emirp numbers.
No, it is not.
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
The first three prime numbers are 2,3 and 5.
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
120
the sum of the first three numbers is 1 + 3+5= 9

product = 6 first three positive counting numbers = 1, 2, 3product of the first three positive counting numbers:1 x 2 x 3 = 6
The sum of the first three prime numbers that end with a 9 (19,29,59) is 107

The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.
