Question

How do you write the prime factorization of `-38mnp`?

Answer 1

`-38mnp = (-2xx19xxmxxnxxp)`

Explanation:

Prime factorisation can also be called writing in expanded form.

`-38mnp = -(2xx19xxmxxnxxp)`

A single variable such as `x` can be regarded as prime, because without knowing a value which it represents, it can only be written as: `x = 1 xx x` There are only 2 factors.

Note: no negative numbers are prime.
