Question

how many numbers exactly have 5digits​

Answer 1

Answer:

90000

A simple idea: The Place Value of Numbers

The smallest 5 -digit number is 10000, while the largest 5 -digit number is 99999. These 90000 possible 5 -digit numbers can have any number from 0 to 9 in any of the places, except for the placement of zero such that there is no non-zero number to its left.

Answer 2

Answer:

The largest 5 digit number is 99999.

99999 minus 10000 is 89999, but since you have a zero-based count, you have to add 1.

That means there are a total of 90,000 different 5 digit numbers.

Hence, there are 90,000 5-digit numbers.
