## Exponents laws and rules

The exponent formula is:

a n = a×a×...×a

n times

The base a is raised to the power of n, is equal to n times multiplication of a.

For example:

25 = 2×2×2×2×2 = 32

##### Multiplying exponents

an · am = an+m

Example: 23 · 24 = 2(3+4) = 27 = 128

an · bn = (a · b) n

Example: 32 · 42 = (3·4)2 = 122 = 144

##### Dividing exponents

an / am = an-m

Example: 25 / 23 = 2(5-3) = 22 = 4

an / bn = (a / b) n

Example: 82 / 22 = (8/2)2 = 42 = 16

##### Power of exponent

(an)m = an·m

Example: (23)4 = 2(3 · 4) = 212 = 4096

m√(an) = an/m

Example: 2√(26) = 2(6 / 2) = 23 = 8

##### Negative exponent

a -n = 1 / a n

Example: 2-3 = 1 / 23 = 1 / 8 = 0.125

##### Zero exponent

a 0 = 1

Example: 40 = 1
