Answer:

Step-by-step explanation:

Given Explain why 7x11x13+13 and 7x6x5x4x3x2x1+5 are composite numbers

The numbers which are not prime and numbers having factors other than one and itself are known as composite numbers.

Now we have 7 x 11 x 13 + 13

we can write as (77 + 1) x 13 = 1014

So factors are 13 x 13 x 3 x 2 which has the value equal to 1014 and has more than one factor. So it is a composite number.

Now we have 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5

We can write as 5(7 x 6 x 5 x 4 x 3 x 2 x 1 + 1)

We get 1009 x 5 = 5045 which is a composite number.

So factors are 1009 x 5 which has the value equal to 5045 and has more than one factor. So it is a composite number.
