Question

explain why 17*5*11*2+2*11 is a composite number..​

Answer 1

As it is

$17 \times 5 \times 11 \times 2 + 2 \times 11$

$11(17 \times 5 \times 2 + 2)$

$11 \times 172$

So it have two factor other than 1 and itself so it is a composite no.

Answer 2

Step-by-step explanation:

We have,

→ ( 17 × 11 × 2 ) + ( 17 × 11 × 5 ) .

= ( 17 × 11) ( 2 + 5 ).

== ( 17 × 11 × 7 ) = x [ Let ].

Thus, the number x has 3 factors i.e., 17 × 11 × 7.

And, we know that composite numbers are those numbers who have more than 2 factors.

Therefore, the number x is a composite number as it has 3 factors.

Hence, it is solved.
