We then practiced with scientific notation and explored the effects of exponential growth on a retirement program (lesson, pdf).

Your homework for Friday is:

- Check the portal
for the results of your assessment, fill out your student checklist
with your results, and make a plan for retake (if necessary),
including making an appointment.
- On your personal blog, create a new post titled: "Scientific Notation"
In the post explain to your reader how to solve this problem:

Multiply, then write your answer in scientific notation: (4.5 x 10^{11})(3.1 x 10^{4})

Make sure you thoroughly explain the steps and what you are doing*so that someone that doesn't know how to do scientific notation can understand it*. (Hint: Just in case, the correct answer is 1.395 x 10^{16}).

Remember, three ways you can "type" exponents on the blog:

1) Use the ^ key (shift-6). So 5^2 is 5 to the second power. This is the easiest way and probably the way most of you will do it.

2) Create an image using the tools I showed you first semester, then upload that image.

3) If you're into HTML, the code for superscript is <sup>, so you have to switch to HTML mode (there's a button at the top of your blog post window that says Compose, right next to it is HTML) and insert the code on the HTML screen. The code would look like this: 5 <sup>2</sup>

When you switch back to the compose window, you'll see a nicely done exponent.

Then visit the moodle and paste in the URL of your blog post. - Prepare for the Scientific Notation Assessment on Friday . Please study.
