Question

Define fundamental  theorem of arithmetic and then explain why 17+11×13×17×19 is a composite number. ​

Answer 1

Answer:

13( 78)

Step-by-step explanation:

undamental Theorem of Arithmetic =" every composite number can be expressed or factorise as a product of primes, and this factorising is unique apart from the order in which the prime factors occur."

★it simply says that every composite number can be factorised as a product of primes.

★composite number= number having more than two factors i.e. other than 1 and itself are called composite numbers

= 7 x 11 x 13 + 13

(taking 13 as common)

= 13(7 x 11 x 1+1)

= 13( 77+1)

= 13( 78)

we can see that the given expression has more than two factors, hence it is a composite number
