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.
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.
When you edit a unit, double brackets appear around it.
