Answer 2

Heya!!!

here's your answer friend,

I) 7 x 11 x 13 + 1

your question is wrong

see its a question

1) 7 x 11 x 13 + 13
it is a composite number because

; 13(7 x 11 x 1 + 1 )
13(78)
here it has a factor 13
therefore it is a composite number

2) 7 x 6 x 5 x 4 x 3 x 2x 1 +5
here 5 ( 7 x 6 x 1 x 4 x 3 x 2 x 1 + 1)
here it have a factor 5
so its a composite number
