Question 752368
LOOK at the pattern to any number raised to integers above and below zero including zero.  When you see the rules of exponents, you understand {{{x^0=1}}}, {{{y^0=1}}}, {{{m^0=1}}}, {{{(x+y)^0=1}}}.  


What does {{{b^-1}}} mean?  It means {{{1/(b^1)=1/b}}}.


What would be {{{b^3/b^1}}}?
How about {{{b^3/b^2}}} ?
Let' keep going.
What is {{{b^3/b^3}}}?





One important rule about exponents is like this:
If m and n are integers, then {{{b^m/b^n=b^(m-n)}}}.

You will plainly know that if m=n, then {{{b^m/b^n=1}}}.
