Exponentiation (^)
	$\scriptstyle {\text{base}}^{\text{exponent}}\,=\,$	$\scriptstyle {\text{power}}$
nth root (√)
	$\scriptstyle {\sqrt[{\text{degree}}]{\scriptstyle {\text{radicand}}}}\,=\,$	$\scriptstyle {\text{root}}$
Logarithm (log)
	$\scriptstyle \log _{\text{base}}({\text{anti-logarithm}})\,=\,$	$\scriptstyle {\text{logarithm}}$

In exponentiation, the base is the number b in an expression of the form bⁿ.
