Well open this section with the definition of the radical. This function also contains a square root cubed roots or any of the nth root. On a side note let me emphasize that evaluating an expression to find its one value and.
Any equation having a radical sign can be solved by isolating the term having the radical sign.
Note that the value of the simplified radical is positiveWhile either of 2 and 2 might have been squared to get 4 the square root of four is defined to be only the positive option 2That is the definition of the square root says that the square root will spit out only the positive root. A radical function is any function that is defined in a root. The method for solving radical equation is raising both sides of the equation to the same power. An equation that contains a radical expression is called a radical equation.
