rationalize(expr)

Parameters

expr

multivariate radical expression

Description

• 

The function rationalize attempts to rationalize the given expression, removing all roots from the denominator.

• 

rationalize does not operate inside transcendental functions, such as exp and sin. Radical expressions that are arguments to such functions within expr will not be rationalized.

• 

In cases where rationalization would lead to a 0 denominator, radnormal is first used to try to simplify the expression, which might result in a numeric exception. If radnormal has no effect, the input is returned unchanged.
