Answer 2

A. 720

Explanation:

The exclamation mark "!" place after a number is called the factorial symbol. It means to multiply all whole numbers from the given number down to 1.

`\begin{aligned}6!&=6 * 5 * 4 * 3 * 2 * 1\\&=30 * 4 * 3 * 2 * 1\\&=120 * 3 * 2 * 1\\&=360 * 2 * 1\\&=720 * 1\\&=720\end{aligned}`

Therefore, 6! = 720.
