Answer:
2⁴x5.
Explanation:
A prime factorization is a operation of multiplied prime numbers that equal the factorized number. Prime numbers are infinite, but some of them are 2, 3, 5, 7, 11.
If have to try to get to 80 by multiplying values from this list. We can't get there by multiplying just 2, therefore we'll have to use other numbers. Doing 2x2x2x2x5 we can get 80. To simplify this, 2x2x2x2 is equal to 2⁴, therefore, the answer is 2⁴x5.
The rule for prime factoring is to get to the number we are factorizing by multiplying prime numbers, tryong to always use the smaller prime numbers.
