Powers & Roots
MTH 4-06b
To run the tutorials simply click on the video you wish to play remembering to pause the video when attempting the questions! You should work through the exercises and homework in a squared jotter to keep all your work together. You should mark every section as soon as you finish it and write down your score.
For certain areas you will need a scientific calculator like the casio fx-85GT PLUS.
Once you have practiced the skills, be sure to see if you can apply them in the exam questions at the bottom of the page. These questions should be revisited every so often as it is important to revise previous work so you don't forget it.
Good luck! :)
Skills developed in this module;
- Writing large and small numbers in Scientific Notation
- Changing numbers written in Scientific Notation back into number form
Bronze Level
In this bronze module we learn how to write big/small numbers in scientific notation and vice-versa. This lesson should be quite straight forward as all numbers only have one non-zero digit.
Video 23: Outcome 1 - Changing large numbers into scientific notation. Grab a pen and your Rigour jotter. Make sure you try all the questions!
