The prime factorization of 4, expressed using exponents is [tex]2^2[/tex]
A factorization process in which the constituent factors are prime numbers only, is called prime factorization.
Prime numbers are those numbers who can't be fully divided by any smaller positive integer, except 1.
Factorization is expressing the given number as multiplication result of smaller positive integers.
[tex]15 = 3 \times 5[/tex] is prime factorization of 15 as 3 and 5 both are prime numbers.
Thus, 4 can be prime factorized as:
[tex]4 = 2 \times 2[/tex] (since 2 is a prime).
Converting it using exponents
[tex]4 = 2^2[/tex]
Thus, the prime factorization of 4, expressed using exponents is [tex]2^2[/tex]
