Six is a semiprime (the product of two primes). Its name, written in English, has 3 letters and 3 is one of the two primes that produce 6.

What 2-digit semiprime is like that?

What is the smallest such 3-digit semiprime?

What is the smallest such 4-digit semiprime?

Consider two cases for each:

• Use the word "and" in all numbers such as "one-hundred and one".
• Don't use the word "and" in those numbers.

In any event, don't use locutions such as "nineteen hundred"; rather, use "one thousand nine hundred" for this example.
