Question

I WILL MARK BRAINLIEST WHAT DOES THIS MEAN????

Answer 1

Answer:

The answers are: 1 and 1.

Step-by-step explanation:

I believe they are how combinations are written. In other words:

$_{n}C_{r}=(\frac{n}{r})=n!/(r!(n-r)!)$ (Ignore the fraction bar, I can't really format it properly).

Anyways, simply find the combination of each:

$(\frac{9}{0})=9!/(0!(9-0)!)=9!/9!=1$

$(\frac{9}{9} )=9!/(9!(9-9)!)=9!/9!(0!)=9!/9!=1$

Note that 0! equals 1.
