This lesson is a review of evaluating exponential values and a precursor to solving exponential equations.
Watch the following video. It is a clip of a Vi Hart video, and the link is also in today's lesson plans.
Stop after watching the first minute, and answer the following question.
How is multiplication similar to counting by addition? Write 1-2 full sentences and give an example.
Since division is the inverse operation of multiplication, it is related when you count by adding. State one item you have noticed or wondered in the first minute and forty five seconds of this video.
Explain how counting in exponentiation is different than counting by multiplication or addition(around 2 minutes in). Please write 1-2 sentences.

What happens when our exponent is zero?
Evaluate.
What happens to our base when the exponent is negative?
If
Evaluate.
Evaluate.
Evaluate. Remember that this means a half count of multiplication to 9.
Evaluate. Remember that this means a fourth count of multiplication to 9.
Evaluate. Remember that this means a 3/4 count of multiplication to 9.
You will remember that the base of an exponential expression is the big number we are multiplying by. What happens when the base is a fraction?
Evaluate.
