Answer:
8589934592
Step-by-step explanation:
Given:
Set of octal numbers = { 1, 2, 3, 4, 5, 6, 7, 8}
total number in the set = 8
Now,
The number is to be formed of 11 digits
i.e
we have 11 places to fill will the numbers given in the set
thus,
we have 8 choices for the single place in an 11 digit number
therefore,
total number of octal number that can be formed = qⁿ
here,
q is the number of choices
n is the number of places to be filled
thus,
total number of octal number that can be formed = 8¹¹
or
8589934592 octal numbers of 11 digits can be there
