Work Shown:

Side note: you can use the nCr formula to compute
; however, it's much quicker to use the shortcut formula
. You can also use Pascal's Triangle to find the value of 
To figure out your question, just divide 999,999 by 9.
999,999/9 = 111,111
Step-by-step explanation: To simplify, we will apply the <em>Quotient Rule</em>.
The 5's in this problem are bases so as you apply the quotient rule,
subtract the exponents but leave the base alone to get 5⁴.
We can also write 5⁴ as 5 · 5 · 5 · 5.
