Question

explain why 7*11*13+13 and 7*6*5*4*3*2*1+5 are composite numbers?​

Answer 1

Answer:

Step-by-step explanation:

FIRST YOU SHOULD DO THE EQUATION 1 AND NEXT 2

= 7*11*13+13

= 13[(7*11*1)+1]

= 13 [77*1]

AS THIS IS PRODUCT THIS IS A COMPOSITE NUMBER AS IT IS PRODUCT OF TWO NUMBERS

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

= 5[7*6*4*3*2*1+1]

= 5[1008+1]

= 5*1009

AS THIS IS ALSO PRODUCT OF TWO NUMBERS THIS IS ALSO A COMPOSITE NUMBER
