Hi!
<h3>To find the prime factorization of a number, keep dividing by the smallest factor that goes into it. </h3>
27/3 = 9
9/3 = 3
3/3 = 1
<u>3 · 3 · 3 = 27</u>
<h2>The answer is C. 3 · 3 · 3</h2>
Hope this helps! :)

58^(1/2) is √58 if that is what you meant
1 joule = 6,242e+18ev
20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev
1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.
