Question

(17x11x2) +(17x11x5) is a composite number? explain

Answer 1

A composite number is a number which has factors other than 1 , itself that is more than 2 factors.

Let's prove that, The given number has other factors than 1 , itself.

( 17 * 11 * 2 ) + ( 17 * 11 * 5 )

= 17 ( 11 * 2 + 11 * 5 )

= 17 ( 11 ) ( 2 + 5 )

= 17 ( 11 ) ( 7 )

The given number has other factors like 7 , 11 , 17 . Hence, It is a composite number

Answer 2

heya mate here your answer goes like this

There are 2 sets of numbers prime and composite

numbers having more than 2 factors rather than one and itself is called composite number

lemme say the proof

( 17 × 11 × 2 ) + ( 17 × 11 × 5 )

17 ( 11×2 + 11×5 )

17 ( 11 ( 2+5 ))

17 (11) (7)

so the factors of a number are 17,11,7

so it is a composite number
