(a)
Evaluate each of the following:
(i)
10! X 20!
17! X 9!

Step-by-step explanation:

1)

Given the expression

Now, multiplying the result

so

Thus, we conclude that:

2)

Given the expression

Now, multiplying the result

so

Thus, we conclude that:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
