It is: 23*32 = 72
It is: 72 = 49
142 = 196 = 22*72
5 x 72 = 245
Exponent form is a short way of notating the number of times a factor repeats. 2 x 2 x 2 x 3 x 3 = 72 23 x 32 = 72
List the prime factorization of the number by exponents. Remember that if a number does not have an exponent, the exponent "1" is implied. Add one to each exponent and multiply. That is the total number of factors. 2^3 x 3^2 = 72 4 x 3 = 12 72 has twelve factors. If there is only one prime factor, add one and there you are. 2^4 = 16 16 has five factors.
2^6
22 x 51
3 x 52 = 75
18 = 2 x 32
Prime factors in exponent form: 2^2 * 17
Prime factors in exponent form: 5^2 * 13
