# Some facts

• Root extraction is an operation inverse to exponentiation.
• The root of n-th degree from the number x is equal to y when y raised to the n-th power gives x:
$\sqrt[n]{x} = y \Leftrightarrow y^{n} = x$
where:
• $n$ - root degree,
• $x$ - root argument (number under root function),
• $y$ - root result (a number, that gives an root argument if raised to root degree).
• The root of degree 2 is colloquially called the square root. It has been assumed that we can omit degree while writing square root symbol:
$\sqrt{x} = \sqrtx$
• The root of degree 3 is colloqually called the cubic root.
• The root from product is equal to the product of roots:
$\sqrt[n]{x y} = \sqrt[n]{x} \cdot \sqrt[n]{y}$
• The root from quotient is equal to quotient of roots:
$\sqrt[n]{\frac{x}{y}} = \frac{\sqrt[n]{x}}{\sqrt[n]{y}}$
• In order to render the root symbol $\sqrt[n]{x}$ in the $\TeX$ language use command:
\sqrt[n]{x}
