Answer 1

hey.... Mate here's ur answer !!

Question : 6

solution = 7 × 11 × 13 + 13

= 13 × ( 7 × 11 + 1 )

= 13 × ( 77 + 1 )

= 13 × 78

it can be also written as ,

= 13 × 13 × 6


the given expression has 6 and 13 as its factor other than 1 and no. itself

therefore,
it is composite number.


now,

7 × 6× 5× 4×3×2×1+ 5

= 5( 7 × 6× 4×3×2×1 + 1 )

= 5 ( 1008 + 1 )

= 5 × 1009

1009 cannot be factorized further
the given expression has 5 and 1009 as its factor other than 1 & no. itself



Hence it is a composite no.
