38.=721.8 it's really just a matter of multiplication. I only have he answer for this one but, y'know, work and whatnot. If you would multiply 3 by 3 than wou would do the same for this problem
We factor out primes from 32 to find it's prime factorization.
32=2*16=2*2*8=2*2*2*4=2*2*2*2*2. 2 is a prime number, so this cannot be reduced further. Since we have five twos and no other primes, the factorization is 2^5, and the only prime factor is 2.
