SymbolDefinitionExample
\( \sqrt a\) Square root - \(\sqrt a \;\times\; \sqrt a = a\) \(\sqrt 9= 3\)
\(^3\sqrt a\) cube root - \(^3\sqrt a \;\times\; ^3\sqrt a \;\times\; ^3\sqrt a = a\) \(^3\sqrt 9 = 2.08008382305\)
\(^4\sqrt a\) 4th root - \(^4\sqrt a \;\times\; ^4\sqrt a \;\times\; ^4\sqrt a \;\times\; ^4\sqrt a = a\) \(^4\sqrt 9 = 1.73205080757\)
\( ^n\sqrt a\) n-th root \(n=5\;\), \(\;^n\sqrt 9 = 1.55184557391\)
