Easily simplify expressions containing exponents | Purplemath
https://www.purplemath.com/modules/simpexpo.htm
WEBPurplemath. We have three basic rules for combining exponents: an · am = an+m. \small { \dfrac {a^n} {a^m} = a^ {n-m} } aman =an−m. ( an) m = anm. However, when simplifying expressions containing exponents, don't feel like you must work only with, or straight from, these rules. It is often simpler to work directly from the meaning of exponents.
