What is prime factorization in exponent form?

Answer 1

Sometimes prime factorizations have repeated factors. It is often easier to write them with exponents.

2 x 2 x 2 x 3 x 3 x 3 = 216

2^3 x 3^3 = 216

When prime factors are repeated, it saves space to use exponents.

2 x 2 x 2 x 3 x 3 x 3 = 216

2^3 x 3^3 = 216

It's a short way to count the repeated factors.

2 x 2 x 2 x 3 x 3 = 72

2^3 x 3^2 = 72
