Units[Standard]

 sqrt
 the square root function in the Standard Units environment
 root
 the nth root function in the Standard Units environment
 surd
 the non-principal root function in the Standard Units environment

Calling Sequence

 sqrt(x) $\sqrt{x}$ root[n](x) $\mathrm{root}[n]\left(x\right)$ root(x, n) surd(x, n)

Parameters

 x - algebraic expression n - integer

Description

 • The sqrt(x) function takes the square root of the unit-free portion of x and multiplies it by the unit raised to the power 1/2.
 • The root(x,n) and root[n](x) functions take the nth root of the unit-free portion of x and multiply it by the unit raised to the power 1/n.
 • The surd(x,n) function takes the nth root of the unit-free portion of x, whose (complex) argument is closest to the unit-free portion of x, and multiplies it by the unit raised to the power 1/n.
 • For other properties, see the global functions sqrt, root, and surd.

Examples

Notes:

 – To enter a unit in 2-D Math input, select the unit from the appropriate Units palette. If the unit you want is not there, select $\mathrm{unit}$ and then enter the unit.
 – In Maple 2015 and later versions, the double brackets around a unit are not displayed unless you are editing the unit.
