Question

Explain why 7 x 11 x 13 + 13 and
7 X 6 X 5 X 4 x 3 x 2 x 1 + 5 are
composite numbers.
(AS)
​

Answer 1

Step-by-step explanation:

any number is said to be composite if has more than two factors (more factors than 1 and itself)

so your question is that all the numbers here are prime so how can the final result be composite

the thing is the change in mathematical operators like multiply and addition both are combined here

example.

13 is a prime no. but 13+13= 26 which is a composite number

Hope your doubt is cleared
