Question

Explain why

$17 \times 5 \times 11 \times 3 \times 2 + 2\times 11$
Is a composite number...........

Please explain properly....... ​

Answer 1

As the no:

17*5*11*3*3+2*11

It has all the factors prime and it also contains 2 as it's factor thus we infer that it is divisible by 2 and all of it's other factors.

Therefore it's a composite no.

For example it you take a composite no. such as 558, Then it's factorisation would be:

558: 2*3*3*31 = 2*3*3*30+1

Here, we can see that it has the prime factors and it's also a composite no.

Answer 2

HERE GUVEN THE NUMBER IS :-

17 ×5 ×11 × 3 × 3 + 2 × 11

SEE THAT IS IT HAS ALL THE PRIME FACTORS AND ALSO IT HAS 2 AS ITS PRIME FACTOR.

AND IG IS CLEAR THAT IT CAN BE DIVISEBLE BY 2, SO ITS ALL OTHER PRIME FACTORS WILL DIVISIBLE BY 2.

@ SO WE CAN SAY THAT IT IS A COMPOSITE NUMBER. ✅✅✅✅✅✅✔

HOPE ITS HELP YOU ☺☺☺☺☺
