Class 10 Exercise 1.2 Question No.6 Solutions

Number are of two types – prime and composite. Prime numbers can be divided by 1 and only itself, whereas composite numbers have factors other than 1 and itself.!

It can be observed that 7 × 11  × 13 +13 ( 7 × 11 + 1)

= 13  (77 + 1)

=  13 × 78

=  13 × 13 × 6

The given expression has 6 and 13 as its factors. Therefore, it is a composite number.

= 7×6×5×4×3×2×1+5

= 5 (7×6×5×4×3×2×1 +1)

 = 5 × (1008 + 1 )

=   5 × 1009

1009 cannot be factorised further. Therefore, the given expression has 5 and 1009 as its fac tors. Hence, it is a composite number.
