A company assigns a number to each member by choosing 8 digits between 4 and 8 inclusively. How many possible membership numbers are there?
since there are 5 choices for each digit, there are
5^8 choices for the number
what does the symbol ^ mean does it mean multiply???
To find the number of possible membership numbers, we need to calculate the number of choices for each digit and then multiply them together.
Since each digit can be chosen between 4 and 8 inclusively, there are 5 choices for each digit (4, 5, 6, 7, or 8).
Since there are 8 digits in the membership number, we need to multiply 5 by itself 8 times:
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 5^8 = 390,625
Therefore, there are 390,625 possible membership numbers.
