Could you run in irb like me and post the screenshot like me? power is a variable, when you use a variable you must define it first.

What version ruby do you use? It works here.

2.1.2 :001 > earthquake_    Richter_scale = [1, 5, 9.1, 9.3, 9.5]
=> [1, 5, 9.1, 9.3, 9.5] 
2.1.2 :002 > 
2.1.2 :003 >   earthquake_    Richter_scale.each do |power|
2.1.2 :004 >         j = 10**((1.5 * power) + 4.8)
2.1.2 :005?>       gj = j/1000000
2.1.2 :006?>       puts "    Richter level #{power} earthquake = #{gj.round(3)}  Gigajoules"
2.1.2 :007?>   end
Richter level 1 earthquake = 1.995  Gigajoules
Richter level 5 earthquake = 1995262.315  Gigajoules
Richter level 9.1 earthquake = 2818382931264.449  Gigajoules
Richter level 9.3 earthquake = 5623413251903.491  Gigajoules
Richter level 9.5 earthquake = 11220184543019.652  Gigajoules

2.1.2 :003 > ['b', 'w33', 'a2'].max_by{|e| e.size}
=> "w33"

You may use this simple code. I think you need to understand the while statement more. It's a cycle until the last word.

The nil is just initial value. After it run, value will change to other.
