Properties of Exponents

2. Rules of Exponents a0 = am•an = a-n = am÷an = (am)n = a(m/n) = 1 am+n
Why ?
= a(1-1) = a0
am+n
Why ?
a2•a3
= a•a•a•a•a
= a5
1/(an)
Why ?
= a-2
a(m-n)
Why ?
= a1
am•n
Why ?
= a8
Why ?

3. = a1 Division is to multiply by the reciprocal Conclusion
If you have a negative exponent in a fraction
“flip” it and make the exponent +
