Question

Evaluate the expression.

4! • 3!

Answer 1

Answer:

Step-by-step explanation:

The answer is 4!·3!=144

the ! is interesting. it goes like this:

1!= 1

2!=2

3!=6

4!=24

this happens because each ! will multiply the number by the answer to the number before it. it is easier to show you though.

1!=1 because 0!=1, and 1*1=1

2!=2 because 1!=1, and 2*1=2

3!=6 because 2!=2, and 3*2=6

4!=24 because 3!=6, and 4*6=24.

so 4!=[(24)*(6)]=3!

24*6=144
