6.1 Integer Exponents and Scientific Notation

Product Rule for Exponents
If m and n are natural numbers and a is any real number then a^m*a^n=a^m+n
When multiplying powers of like bases keep the same base and add the exponents.

If a is any nonzero real number then a^0=1

Negative exponent
For any narural number n and any nonzero real number a a^-n=1/a^n

Special Rules for Negative Exponents
If a is does not equal 0 and be does not equal 0 then 1/a^n=a^n and a^-n/b^-m=b^m/a^n


If a is any nonzero real number and m and n are integers, then a^m/a^n=a^m-n
