What is the prime factorization of 72?
Prime factors of 72 are 2 and 3. Product of the given prime factors = 2 × 3 = 6.
How do you write 72 in exponential form?
Answer. Answer: We see that after the factor tree for 72 is complete, the prime numbers at the end of the branches are 2, 3, 2, 3, and 2. Thus, we have three 2’s and two 3’s in the prime factorization of 72, so we write this in exponential form as 23 × 32.
What is exponential form in prime factorization?
The method of prime factorization is used to “break down” or express a given number as a product of prime numbers. More so, if a prime number occurs more than once in the factorization, it is usually expressed in exponential form to make it look more compact.
