I've provide a list of 7 "laws" that I think you should be aware of.

However, as noted, you could derive more variations of these and some of them could be derived from others.

#### Explanation:

Here are the one's that I would consider essential:

#a^0=1# provided#a!=0# #a^1=a# #a^(p+q)=a^p * a^q# #a^(p * q) = (a^p)^q=(a^q)^p# #a^(-b)=1/(a^b)# #a^(1/b)=root(b)(a)#

plus, more as a definition

#a^b=c hArr log_a c = b#

A few of these are derivable from others and you could extend this

by deriving different forms.
