73 satisfies your condition.
Find 5 four digit numbers such that the product of the digits of each four digit prime number are also prime?
You had me until "product." The product of 4 digits can't be prime.
What is the smallest two-digits prime number whose digits are also prime themselves?
23

What are the reversible prime numbers?
A reversible prime is a number such as 37, where reversing the order of the digits gives 73 which is also a prime.

10.) A two-digit number is prime. When you reverse the digits, that number is also prime. What could the number be List three possibilities.?
Some numbers that you can get when you reverse the digits and they are still prime numbers are: 403 ÷ 13 = 31 2,701 ÷ 37 = 73 1,207 ÷ 17 = 71

What is the smallest two-digits prime number whose digits are also prime themselves?
23
Are there infinitely prime numbers?
Yes. As infinity is so vast, and massive.. well infinite to be honest, there are also infinite prime numbers. The only difference is that they are few and far between. For instance, in low digits, they occur a lot more frequently (2, 3, 5, 7, 11, 13, 17) And that's just in the space of 20 numbers. However, as they get bigger, the gaps between them are much larger. Currently, the highest know prime number is [(243112609) -1], a number 12978189 digits long. (For some perspective 1,000,000,000,000 is only 13 digits) The prime number right below that is [(237156667)-1] and is only 11185272 digits long. Therefore, the higher prime numbers get, the further apart they are.
How many prime numbers are in the prime factorization of 51?
The digits in 51 add up to 6, so it is divisible by 3.51/3 = 17 (17, like 3 is a prime number)so the prime factors of 51 are the two numbers, 3 and 17(51, like all numbers, can also be divided without remainder by 1, but this is not usually counted as a prime factor)
