Question

Explain why (7x13x11)+11 is a composite number

Answer 1

Answer:

In (7×13×11) +11 there are two numbers: (7×13×11) and 11. We can easily find a common factor between these two numbers i.e. 11. The numbers which has any common factor other than 1 is a composite number. Hence, (7×13×11) +11 is a composite number.

Answer 2

Answer:

Because 1012 is divisible with other numbers and it has more than two factors

Step-by-step explanation:

According to BODMAS rule we must should Bracket So in bracket it is 7x13x11

7x13=91 and 91x11=1001

After Bracket There is Addition So 1001+11=1012

Factors of 1012 are1, 2, 4, 11, 22, 23, 44, 46, 92, 253, 506, 1012 which is more than two factors so it is composite no.
