1.	Is 7power5×3 square×5+3 is a composite number ? Justify your answer
Answer» Answer: Yes Step-by-step explanation: 7^5 × 3^2 × 5 + 3 = 3 ( 7^5 × 3 × 5 + 1) since this is a PRODUCT of prime numbers....it's a COMPOSITE number note : if the number (7^5 × 3 × 5 + 1) is prime our assumption is obviously right. EVEN it's not prime, it can be surely expressed as a product of prime by factorisation
