Properties of Exponents Foldable
Exponential Expressions: expressions that contain exponents.
Exponents
Base: Number being Multiplied
Exponents: How many times the base is used as a factor
Negatives
No Parenthesis ­ Negative goes straight to answer
Parenthesis ­ Negative goes with the problem (use it to solve)
3 Exponent
4
BASE
If you substitute a number for a variable use parenthesis.
4 4 4 = 64
Examples: (­5)4 = (­5)(­5)(­5)(­5) ­62 = ­(6 6) Any base raised example:
to the power of 41 = 4
______ is equal b1 = b
to _______.
(Note: Any number or variable without an exponent has an exponent of 1.)
Identity Property of Exponents
Any nonzero base Zero Exponent raised to the power Property
of ______ is equal to _______.
example:
50= 1
a0 = 1
(Note: 00 is undefined)

Can you find a pattern or shortcut from writing it all the way out each time? 43 42 = (4 4 4)(4 4) = 45 Dec 16­2:29 PM
To ___________ powers with the Product Rule
same base, _____ the exponents. a4 a6 = (a a a a)(a a a a a a) = a10
example:
32 35 = 37
a7 a4 = a11
x3 x x4 = (x x x)(x)(x x x x) = x8
