1.	Explain why 7×11×13+13 and 7×6×5×4×3×2×1+5 are composite numbers?
Answer» That is why both no. Are composite Numbers are of two types - prime and composite.Prime numbers can be divided by 1 and only itself, whereas composite numbers have factors other than 1 and itself.It can be observed that=\xa0=\xa0=\xa0The given expression has 6 and 13 as its factors other than 1 and number itself.Therefore, it is a composite number.=\xa0=\xa0=\xa01009 cannot be factorized furtherTherefore, the given expression has 5 and 1009 as its factors other than 1 and number itself.Hence, it is a composite number. ,xdhh
