The document discusses laws of exponents and their applications. 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 power of zero equals one. The document then provides examples of using these laws to find missing exponents, simplify expressions, and write expressions as powers of 10.

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 =
ONE!!
