Numbers formed should be of at least 3 digits means they may be of 3 digits, 4 digits, 5 digits or 6 digits. There are 6 choices for digit in the units place. There are 5 and 4 choices for digits in ten and hundredโ€™s place respectively. So, total number of ways by which 3 digits numbers can be formed = 6.5.4 = 120 Similarly, the total no.of ways by which 4 digits numbers can be formed = = 360. the total no. of ways by which 5 digits numbers can be formed = = 720. The total no.of ways by which 4 digits numbers can be formed = = 720. So, total no.of ways by which the numbers of at least 3 digits can be formed = 120 + 360 + 720 + 720 = 1920.

If in some country you have, say, 5 million mobile devices, you need at least seven digits.Mobile numbers may have to start with certain digits. This may require an additional digit. In the above example, if in a country all mobile phone numbers start with 6, 7 or 8, then 7 digits are no longer enough - the minimum requirement is 8 digits.The numbers may be organized so that the first few digits identify the phone company, or the geographical region. This also tends to increase the number of digits, since some areas will have few numbers, while others will have many.

Are irrational numbers always decimal numbers?

Both rational and irrational numbers can be expressed with decimals. If the number is irrational, it will have an infinite number of decimal digits, and there will be no periodic repetition.
