1. 5.4 Scientific Notation

2. Given a # in Standard Notation write it in Scientific Notation
Move decimal until the # is 1 ≤X <10
Multiply that # by 10 to a power
The power will be the # of times you moved the decimal
If the original # >1 positive power
If the original # <1 negative power

3. Write an equivalent expression using scientific notation:
