Yep! Anything over 1 is just itself.

Awesome, thank you!

I have 5 more problems similar to this. Can I post them here and we can work through them?

Please post them one at a time and yes we can. Start right now!

Okay, awesome. I got 7 wrong in my current lesson, so 5 more to go!

This one was number 13 in my lesson.

13.

Do I use the same method as the last one?

Hi;

Do you know how to use codecogs to post math? If not, I will show you.

You always use the same methods in math. Very rarely is something clever required for school problems. You try first.

Hi SlowlyFading;

Mathematics is a language like English. Like English it has rules. When writing in any language it is important that we are neat so that people can read what we write. I cannot read that at all. If no one can read your work they will just mark it wrong and move on to the next paper. Believe me I know.

We have a long way to go. Go here and look around, tell me when you are there.

Of course that result can be rigorously obtained, but who cares?

Haha, I didn't think you would be able to read that!

Is this better?

And I'm there.

Okay, that is a little better but we will do even better than that.

Codecogs is menu driven. That means everything has a pull down menu. To write a fraction look at the bottom line second from the left. You will see:

click that and on its tiny screen you will see \frac{ }{ }. Got that?

What is this?

Is that x^2 times by 1?

Should it be? Should there be a dot between them?

Hi;

I will be able to answer that as soon as we clean up the original question.

You should be able to do much better writing this now. Please do that.

Hi;

That is getting better. What is that 3 supposed to be?

Okay, now just do what you did in the last problem.

Hi;

That is very good but still not simplified enough. Use the rule about when a number is multiplied or divided by 1.

Hi;

That is not correct.

Start with the first one

x^2 * 1 is equal to what?

It's just x^2 I think.

That is correct. Anything times by one remains the same.

So replace the x^2 * 1 by x^2. Do that now.
