there are 300 lightbulbs lined up in a row in a long room. Each bulb has its own switch and is currently switched off. each bulb is numbered consecutively from 1 to 270. you first flip every switch. you then flip the switch on every second bulb (turning off 2, 4, 6...). you then flip the switch on every third bulb (3,6,9). this continues until you have done the process 300 times. how many of the light bulbs have you illuminated now?

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
