42 and 84
To write a composite number as a product of two prime numbers, write it as an answered multiplication question like 2 x 17 = 34 or 3 x 3 x 7 = 63.
As a product of its prime factors in exponents: 22*3*52 = 300
composite and 2*2*7 = 28
405 = 3 x 3 x 3 x 3 x 5
Yes. Do a factor tree to find the prime factors. Then write down all of those times together equals your original number.e.g. 12=6*2=2*2*3=which is written as two squared*3

2/5 are prime, 8/15 are composite (and 1/15 is neither).
I'm not sure what you mean. But the factorization of a composite number into prime factors is unique, up to the ordering of the primes.
As a product of its prime factors in exponents: 22*3*52 = 300
9 is the smallest natural number that is odd and composite: 9=3*3. 15 is the smallest natural number that is odd and a product of two numbers different from one and from each other: 15=3*5.
composite and 2*2*7 = 28
405 = 3 x 3 x 3 x 3 x 5
Yes. Do a factor tree to find the prime factors. Then write down all of those times together equals your original number.e.g. 12=6*2=2*2*3=which is written as two squared*3
295 is composite - 5 x 59.
It is called the prime factorisation (or prime decomposition) of the composite number.
