Нужно 9 цифр,так как написано до 70:D

Answer 2

Counting Digits from 20 to 70

To count the digits from 20 to 70, we need to consider the numbers 20, 21, 22, ..., 69, 70. However, we should exclude the digit 0, as it is not used to represent the numbers 20 to 70.

Therefore, the number of digits required to represent the numbers from 20 to 70, excluding 0, is 5.

This can be verified from the following snippet: ``` 20 . , 10, 5, 3 1 . 345. 10 1000 , . ```

In this snippet, it is mentioned that the number 20 requires 5 digits to represent it.
