Answer 1

☆To Prove.

1) 13*12*11*10+12.

2) 23*29*31*37+37.

Are Composite numbers.

☆ Now,

=》 13*12*11*10+12 can be writen as,

=》 12 × (13×1×11×10+1).

= 12 × (143×10+1).

= 12 × (1430+1).

= 12 × (1431).

Clearly we can see that 13*12*11*10+12 is divisible by 12, 1431, 1 and itself.

▪︎ Therefore it can be concluded that it is a composite number.

☆ Similarly,

=》 23*29*31*37+37 can be written as,

=》 37 × (23×29×31×1+1)

= 37 × (767×31+1)

= 37 × (23777+1)

= 37 × (23778)

Clearly we can see that 23*29*31*37+37 is divisible by 37, 23778, 1 and itself.

▪︎ Therefore it can be concluded that it is a composite number.
