Question

7*11*13+13 AND 7*6*5*4*3*2*1+5 ARE COMPOSITE NUMBERS PLEASE ANSWER FAST I HAVE A TEST TOMORROW

Answer 1

Yes ,both are composite number.

How?

Here is your solution ➡

$7 \times 11 \times 13 + 13$

$13(7 \times 11 \times 1 + 1)$

$13(78)$

Since 78 is a composite number,when multiplied you will get a Composite Number as well.

Now,second one➡

$7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 + 5$

$5(7 \times 6 \times 1 \times 4 \times 3 \times 2 \times 1 + 1)$

$5(1009)$

This will also give product as Composite number.
