There are an infinite number of them. But if you only count
the whole numbers, then there are only 69 of them.
744 digits.
The numbers from 1 to 39 include both single-digit and double-digit numbers. There are 9 single-digit numbers (1 to 9) and 30 double-digit numbers (10 to 39). Therefore, the total number of digits is 9 (from single-digit numbers) + 60 (from double-digit numbers, as each has 2 digits) = 69 digits in total.
630 digits.
Almost got me on this one. 20 numbers but 29 digits
36
There are the digits 1 through 9 for the first digit. Then, we have 0 through 9 for the second digit - excluding the first digit. For the third digit, we have 0 through 9 excluding the two previous digits
192 digits
There are 2892 digits.
Using only arrangements of the given digits: without repeating digits, 15. with repetition, 39. The answer does not include numbers such as 2^3 = 8 or 3^(2+1) = 27
the main purpose of multiplication is to multiply 1 through as many digits as you want. :)
There are 2700 digits.
