You had me until "product." The product of 4 digits can't be prime.
The product of a 4-digit multiplicand and a 1-digit multiplier can have either 4 or 5 digits. If the 4-digit number is multiplied by a multiplier of 1 to 9, the product will typically have 4 digits. However, if the multiplicand is multiplied by 10 (the maximum value for a 1-digit number), the product can reach a maximum of 5 digits. Thus, the product can range from 4 to 5 digits, depending on the specific numbers involved.

The number of zeros in the product of multi-digit numbers with zeros and one-digit numbers depends on the placement of the zeros in the multi-digit numbers. If a zero is at the end of a multi-digit number, it effectively multiplies the other digits by ten, contributing to the count of zeros in the product. However, if the zeros are located elsewhere, they may not affect the overall count of zeros in the final product. Thus, the final count of zeros can vary based on the specific arrangement of digits.
It can have up to 5 digits.
The product of two two-digit numbers is always at least 100. This is because the smallest two-digit number is 10, and multiplying 10 by itself (10 × 10) yields 100. Since any other combination of two-digit numbers will produce a larger product, it is impossible for the product to remain a two-digit number.
If you mean, "What is the largest number of digits possible in the product of two 2-digit numbers" then 99 * 99 = 9801, or 4 digits. Anything down to 59 * 17 = 1003 will have 4 digits.

-- "The sum of a two-digit number" is unclear. I took it to mean"The sum of the digits of a two-digit number."-- "... the product ?" is unclear. Are you looking for the product of the two digits,or the product of the forward and backward numbers ?-- It's not possible to write a number whose two digits sum to 12 and whosereverse exceeds it by 25. The tens digit would have to be 4.611... and the unitsdigit would have to be 7.388... .Then(4.611...) + (7.388...) = 12(46.111...) + (7.388...) = 53.5(73.888...) + (4.611...) = 78.5Difference = 25So, the number can't be written, but ...The product of its two digits is 34.071 (rounded)The product of the forward and reverse numbers is 4,199.75 (rounded)
To find the last but one digit in the product of the first 75 even natural numbers, we need to consider the units digit of each number. Since we are multiplying even numbers, the product will end in 0. Therefore, the last but one digit (tens digit) will depend on the multiplication of the tens digits of the numbers. The tens digit will be determined by the pattern of the tens digits of the even numbers being multiplied.

The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
It can have one . . . 1.0 x 1.0 = 1 It can have two . . . 1.0 x 0.1 = 0.1 It can have three . . . 10 x 10 = 100 It can have four . . . 99 x 99 = 9801 and .01 x .01 = .0001
73 is the largest two-digit number that is prime and has prime numbers for both of its digits.
It can have 4 digits, because the highest possible two digit numbers 99*99=9801.
