Algebra: Chapter 1, Lesson 3, page 15.
Exponential Notation
A product in which the factors are the same is called a power. We can write `2⋅2⋅2⋅2` as `2^4`. The number 4 is called the exponent and the 2 is called the base. The exponent tells how many times the base is used as a factor. When an expression is written with exponents, we say the expression is written using exponential notation.
Remember, anything to the zero power is = 1, `z^0=1` or `4^0=1` as well. Anything raised to the 1 power is just the number, `y^1=y` and `101^1=101`.
Don’t forget PEMDAS too with the exponents being the second operation to be performed.
I like to use a site called purplemath.com. They have some great explanations about our lessons. See these explanations on exponents too!
