1.	How will you show that (17×11×2)+(17×11×5) is a composite number? Explain.
Answer» ( 17 x 11 x 2 ) + ( 17 x 11 x 5 )By taking ( 17 x 11 ) common ,= ( 17 x 11 ) ( 2 + 5 )= ( 17 x 11 ) ( 7 )= 17 x 11 x 7.If any number can be represented in the form of product of prime numbers then that number is composite number.Hence , ( 17 x 11 x 2 ) + ( 17 x 11 x 5 ) is a composite number.
