Question

Write the prime factorization of 20. Use exponents when appropriate and order the factors from least to greatest

Answer 1

I'd draw a prime factor tree for 20, so:
20 -> 10 × 2 (2 is prime)
10 -> 5 × 2 (both are prime)
So you have 2 × 2 × 5, which can also be written as 2² × 5, which is your answer. I hope this helps!
