What's a Power?

Powers are Exponential Expressions

2

What exactly are the parts of Powers?

It's like when you learned to multiply where you noted how many times you added a number now we note how many times we multiply a number

3

How to write it long hand?

  • Examine the expression

  • Determine what is the base (bottom number)

  • Determine what the exponent is (floating number) This will be your reference number

  • The base will be multiplied to itself as many times as the exponent says

10

Using what we did to expand we can also go to Exponential Notation

  • Find the number being multiplied to itself it will now become the base

  • Count how many times the base is being multiplied (that will be the exponent)

And of Course Special Rules

  • Powers of Zero

  • Negative Powers

  • Don't worry this is only your first time working with exponents and we will only talk about Powers of Zero

Powers Of Zero

Any power expression with an exponent of zero will equal 1
