The digits product of two digit has number four

It can have 4 digits, because the highest possible two digit numbers 99*99=9801.

4 Give examples to support your answer please.

from 3 digits (10x10) to 4 digits (99X99)

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.

You had me until "product." The product of 4 digits can't be prime.

3-4 :p

There are 15 of them.

The answer is 4. You get the answer by trying the example of the largest two digit number, 99. 99 x 99 = 9801. This has four digits, so you can't get more digits than this by multiplying two two digit numbers. * * * * * True, but you CAN have fewer: 10*10 = 100, which is only three digits! 1490 of the 8100 2 digit x 2 digit multiples have products of 3 digits, the rest have 4 digit products.

Take the smallest 2-digit number (10), and see how many digits you get when you multiply it by itself.Also, take the largest possible 2-digit number (99), and see how many digits you get when you multiply it by itself.

There are three such numbers: 12, 24 and 36.

1234, 2637, 7777, 2727 are examples of a four digit number. So any random four numbers are four digits.

With 123 digits you can make 123 one-digit numbers.

There are five such numbers: 11, 12, 15, 24 and 36.

There are 5460 five digit numbers with a digit sum of 22.

If the question is about the product of all odd digits, the answer is 945. Otherwise the question does not make sense.

There are 9 digits that can be the first digit (1-9); for each of these there is 1 digit that can be the second digit (6); for each of these there are 10 digits that can be the third digit (0-9); for each of these there are 10 digits that can be the fourth digit (0-9). → number of numbers is 9 × 1 × 10 × 10 = 900 such numbers.

Forming three three digit numbers that use the numbers 1-9 without repeating, the highest product possible is 611,721,516. This is formed from the numbers 941, 852, and 763.

5040 different 4 digit numbers can be formed with the digits 123456789. This is assuming that no digits are repeated with each combination.

27 three digit numbers from the digits 3, 5, 7 including repetitions.

Using the digits of 1345678, there are 210 three digit numbers in which no digit is repeated.

362,880 edit: 3,628,800 edit: Sorry, Whizkid. You included '10', whereas the question clearly stated "single-digit numbers". Now that we think about it, the "10 single digit numbers" must include zero, so the product is zero. But for the digits 1 thru 9, the product is still 362,880 .

Five.The five numbers are 11, 12, 15, 24, 36
