Question

show that 3 into 5 into 7 plus 7 is composite number ​

Answer 1

Answer:

yes

Step-by-step explanation:

composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number.

The number 111 can be evenly divided by 1, 3, 37 and 111, with no remainder.

Since 111 cannot be divided by just 1 and 111, it is a composite number
