So that tells you that we're always going to be switching one of these light bulbs on or off when one of its factors is our pass.

So if I'm on the second pass, I will I don't want to say turn on.

They all started off, so they're all going to be turned on.

And what I'm going to do is, first I'm going to go and I'm going to switch essentially every light bulb.

Hopefully it simplifies to something.

Let's go up here.

This is the n is equal to zero.

I won't tell you what type these are going to be.

The sarah connor chronicles... Whatever happened with the explosion flipped a switch.

Whatever happened with the explosion,it's flipped a switch.

I know all the light bulbs that are numbered where n is a factor of that light bulb, that will get switched.

And then pass eight is the next time we'll touch this

And just to make it clear, what's the 100th path going to be?

light bulb, every numbered light bulb would that is a multiple of three is going to be switched.

And that's times 1 2 to the sixth.

We can subtract 15 from both sides.

Switches to data view.

Switches to design view.

Switches to text view.

And now we're ready to substitute back in.

So let's do that.

So let me just write all over again.

And I'm trying to free up some space.

Switching to visual scanners.

So 2x goes into this expression 31 4 times and I'll switch colors.

And when you turn the switch on, the light goes on.

Well that equals this, a plus bi, plus this is z sub two right here c plus di.

If you look closely at this device, it's got a switch for encryption or cleartext.

And the inequality will switch, because we are multiplying or dividing by a negative number.
