Introduction

Today, you will learn all about Scientific Notation. A few questions to ask yourself after the lesson...

"What is scientific Notation?"

"How do I write a number in scientific notation?"

"How do I change a number written in scientific notation back into standard form?"

"How do I add and subtract numbers written in scientific notation?"

"How do I multiply and divide numbers written in scientific notation?"

Task

Now, on your own, you need to find the answers to these questions.

1.Why do we use scientific notation?

2.Define scientific notation.

Are these numbers written in scintific notation?

3. 43.882x10^2

4.3.6x10^-56

5.8x10^11

6.2x4^3

Change these numbers back to standard form.

7. 17x10^6=

8. 47x10^17=

9. 3.5x10^-15=

10. 2.8x10^-7=

Change these numbers into scientific notation.

11. 1000000000000=

12. 63000000=

13. 0.000000002=

14. 0.0000394

Solve these equations.

15. 3.2x10^-8+4.5x10^-5

16. 2.2x10^10+8.6x10^11

17. 3.8x10^4-6.2x10^6

18. 1.5x10^56-7.8x10^55

19. 3.29x10^9x8.63x10^23

20. 2.35x10^8x7.89x10^32

21.8.4x10^23/4.7x10^9

22.3.9x10^89/5.6x10^53
