# Thread: Pre calc help

1. ## Pre calc help

Hi would a question say i have a question like this how would i simplify?

300!/200!

Factorial notation

Thanks in advance.

The only ways I can think of offhand to rewrite that, which aren't simplifications per se are:

$\frac{300!}{200!}=100!{300 \choose 100}=\prod_{k=201}^{300}(k)$
