Units[Standard][surd] - the non-principal root function in the Standard Units environment

Calling Sequence

sqrt(x)

x

root[n](x)

rootnx

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 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.
