Question

Explain why 17*5*11*3*2+2*11 is a composit number &check 3*12*101+4is a prime number or composit number

Answer 1

number has 2 and 11 as factors and 3*12*101+4 is composite because it has 3 , 12 , 101 as it's factors

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.
