The document discusses laws of exponents and provides examples of applying those laws. Specifically, it introduces the laws that na x nb = na+b, na / nb = na-b, and (na)b = na x b. It also notes that anything to the zero power is equal to one. The examples show applying these laws to simplify expressions and write them as powers of 10, such as 106 x 103 = 109 and 106 / 102 = 104.

Lesson 27
*laws of exponents – used to describe relationships
between exponents for certain operations
FYI...
na nb = na + b
na
nb = na ­ b
(na)b = na b

Please note...
104 =
103 = **ANYTHING
102 = TO
101 = THE ZERO
then what would 10 0 = ?? POWER =
