Question

a. 9999
b. 10,000
c. 36,000
d. Infinite

Answer 1

There are 9999 natural numbers that have no more than 4 digits.

Step-by-step explanation:

To determine the number of natural numbers that have no more than 4 digits, we can observe that the largest 4-digit natural number is 9999. Therefore, we need to count the number of natural numbers starting from 1 up to 9999.

To do this, we subtract 1 from 9999 to exclude the number 0, and then add 1 since we need to include the number 9999. This gives us a total of 9999 - 1 + 1 = 9999 natural numbers.

So the correct answer is a. 9999.
