### Negative Exponent Law Scribe Post for January 11, 2010

Monday, January 11, 2010
Hello everyone! Nicky here yet again to tell you about our Math class today. First of all, we went over our homework with Mr. B. Then, (once all questions were answered) Mr. B "informed" us that we would be starting chapter 3.4. He also taught us about another of the Exponent Laws. This one is entitled, the "Negative Exponent Law".

Now, just what is the Negative Exponent Law? Defined scientifically (or mathematically I suppose) it is: a nonzero base raised to a negative exponent is equal to the reciprocal of the base to the positive exponent.

Quite a mouthful, eh? Well, don't you worry, never fear, Robin Hood will soon be here... Ahem... Until he does I'll just continue on with the class, shall I?

Hm... Now where was I... Ah yes! Mr B's demonstration of this law... Well, first, I think I'll give a simpler definition considering the one above can be quite confusing... Relatively speaking, the Negative Exponent Law states that when you have a base that isn't zero and you're raising it to a negative exponent, it is equal to the reciprocal of the fraction that you get. (Here's a picture to make it much simpler).Alright. This concludes the lesson on Grade 10/11 stuff... Yeah... We're learning advanced stuff because we're "The Class"... Or, Mr B just wants us to... I amen't sure... Anyway, Robin Hood should be coming right about now to deliver his- Ah! Here he is (took him long enough)!Thank you, "Robin" for your very...er....informative definition of the Negative Exponent Law. I was kind of hoping you'd say something more along the lines of it dealing with patterns and fractions as I demonstrated above but, oh well. Beggars can't be choosers, until Robin Hood gives them money! Harhar... I made a funny (and a rhyme)!

*drumroll* And now, the moment you've all been waiting for, HOMEWORK! *trumpet fanfare*

(The following is due on Wednesday)

Textbook Pgs. 118-119 (All questions)

Workbook Chapter 3.4

Mathlink Chapter 3.4 (Separate Sheet, not in Textbook)

Extra Practice Chapter 3.4

This now concludes our broadcast day. It will resume tomorrow evening with your new "anchor" Mark.

Nicky, check your 3^-1 I think it should read 1/3.

Oopsies... Thinking of the wrong exponent.. Thanks Mr. B

Nice on Nicky, great post. good job on highlighting the definition of Negative Exponent Law, it really stands out. I like how you make up a story, very creative. "Claps! for Nicky"

Great job Nicky! I like how you explained the negative exponent law again, I didn't get it in class at first. Every scribe post you seem to put a story or poem, very creative.

Nice job Nicky! You explained everything well, and I liked your creativity, like what Shaneille said. Thanks for the heads up on homework, and nice colour fonts and pictures. Great scribe (;

Great job Nicky! I really like your scribe for today, very creative. Great use of colour by the way. Thanks for explaining the Negative exponent law, that confused me for a bit in class. Well anyways, great job again!
