Question

explain why 5×11×17+17 is a composite number while 7×6×5×3+5 is not a composite number​

Answer 1

Answer:

It is very easy... we know that every composite number can be written in the form of product of prime numbers... here 5*11*17+17 it is in the form of product of primes.. but 7*6*3*5+5 is also composite number because 6 can be written in 2*3 .

Answer 2

Step-by-step explanation:

$5 \times 11 \times 17 + 17 \\ 17(5 \times 11 \times 1 + 1) \\ 17(55 + 1) \\ 17 \times 56$

it is composite because 17 is a prime no.

if you multiple then only composite no. come
