Answer: a) 10!/7!

<u>Step-by-step explanation:</u>

The "quick" way of answering this is: 10 × 9 × 8 = 720

If you are using the formula then you get:

$\dfrac{10!}{(10-3)!}\quad =\large\boxed{\dfrac{10!}{7!}}\quad = 720$

You always have to switch the inequality symbol when dividing by a negative because a negative always negates a number's (other than 0) original sign.
