Question: what is a prime factors in exponential form?
Answer: The first few primes in order are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Write the unique factors by writing the exponents only up until the zeros start repeating. So 100 = 2 x 2 x 5 x 5 can be written as 2 0 2 and 147 = 3 x 7 x 7 can be written as 0 1 0 2. Written this way each factorization is unique.
