In base 9, 9 is written as 10
So 9^6 becomes 10^6 or 1 000 000

The base 10 representation of 9(exponent 6) is 531,441. What is the base-9 representation of 531,440?
Since 9^6 = 531,441:
531,441 = 1*9^6 + 0*9^5 + 0*9^4 + 0*9^3 + 0*9^3 + 0*9^2 + 0*9^1 + 0*9*0
So the base 9 representation of 531,441 is 1000000.
One less than this is then 0888888 base 9.
