Exponent Laws #4 and #5
These laws are generated (and understood) by extending
an accepted numerical pattern…
The second tier of the exponents laws takes us beyond the range of
“common visualization”
In generalx0 = 1
23 = 8
22 = 4
21 = 2 Continue the pattern
20 =
1 2
x

1 2
x 1
This law holds true for any number!
Any number to the exponent zero always reduces to 1
Continue the previous pattern..
Is there a pattern?
2-1 = 121
2-2 =12

X =
2-3 =12

X =

In General
X-n = 1
• When given a negative exponent, invert the term and change the negative exponent to a positive exponent
Xn
For example:
2-3 = 123
= 18

2 53
=53

(x4)(x3) = x7
(y4)5 = y20
