1. Power and Zero Laws of
Exponents
Week 3 Lesson 3
L.O: I can understand the power and zero laws of exponents and
generate equivalent expressions with exponents.
All: I can explain what power and zero laws of exponents are.
Some: I can identify and use exponent laws. (power and zero)
Few: I can simplify expressions with exponents using the correct rules.

2. Pre-Assessment
L.O: I can understand the power and zero laws of exponents and generate equivalent
expressions with exponents.
All: I can explain what power and zero laws of exponents are.
Some: I can identify and use exponent laws. (power and zero laws)
Few: I can simplify expressions with exponents using the correct rules.

3. Terminology
Term Exponent/Power Base Simplify
Definition A small number
written above and
to the right of a
base. It shows how
many times the
base is multiplied
by itself.
The number that is
multiplied by itself
when raised to an
exponent.
To rewrite an
expression in its
shortest or
easiest form.
Examples 2^4=2×2×2×2=16.In 5^3, the base is 5. Simplify
2^3×2^2=2^5
