Answer 1

hey!!!

3×5×7×11+11

11(3×5×7+1)

Answer 2

$<b>A composite number is a number that is divisible by another number other than by itself and one. The number 2 is the only even prime number. All other even numbers are composite numbers<b>$​

$<b>As per BODMAS rule:<b>$​

$<b>3 x 5 x 7 ×11 + 11 =1166.<b>$​

$<b>1166 is an even number and is therefore a composite number.<b>$​

$<b>Also, 1166 is divisible by other numbers such as 2 ,11, 22 ,53 ,106 ,583 apart from itself (1166) and 1.<b>$​
