Start studying Lesson 5: Working with prefixes and powers of 10. The prefix attaches directly to the name of a unit, and a prefix symbol attaches directly to the symbol for a unit. millimicro). element.src = "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"; Divide the initial power of 10 by the final power of 10. mg not µkg; Mg, not kkg.
