  • (am)(an) = am+n
  • (ab)m = ambm
  • (am)n = amn
  • a0 = 1
  • (-1)Even Number = 1
  • (-1)Odd Number = -1

\[\ Power\; zero = a^{ 0 } = 1\]
\[\ Power \;one = a^{ 1 } = a\]
\[\ Fraction\; formula = \sqrt{ a } = a^{ \frac{ 1 }{ 2 }}\]
\[\ Reverse \;formula = \sqrt{ n } { a } = a^{\frac{ 1 } { n }}\]
\[\ Negative \;power \;value = a^{ -n } = \frac{ 1 }{ a^{n} }\]
\[\ Fraction\; formula = a^{n} = \frac{1}{ a^{ -n } }\]
\[\ Product \;formula = a^{m}a^{n} = a^{ m + n }\]
\[\ Division\; Formula = \frac{ a^{ m }}{ a^{ n }} = a ^{ m-n }\]
\[\ Power\; of \;Power formula = (a^{ m })^{ p } = a^{ mp }\]
\[\ Power \;distribution Formula = (a^ { m }c^{ n })^{ x } = a ^ { mx } c ^{ nx }\]
\[\ The\; Power\; distribution \;Formula = \left ( \frac {a ^{ m }}{c^{ n }} \right )^{x} = \frac{a^{ mx }}{c^{ nx }}\]
