I hope this is helpful to you

Answer 2

Answer:

Step-by-step explanation:

(7*11*13)+(13*1)

take 13 common

13( (7*11*1)+(1*1) )

13( (77)+(1) )

13*78

Number having more than 2 factors (i.e., 1 and itself) called  Composite Number.

(7*11*13)+13 = 13*78

(7*11*13)+13 is composite number because it has more than two factors i.e., 1 and itself.

(7*6*5*4*3*2*1)+(5*1)

take 5 as common

5( (7*6*1*4*3*2*1)+(1) )

5*1008+1

5*1009

Number having more than 2 factors (i.e., 1 and itself) called  Composite Number.

7*6*5*4*3*2*1+5 = 5*1009

7*6*5*4*3*2*1+5  is composite number because it has more than two factors i.e., 1 and itself.
