If n is even, and a ≥ 0, b > 0, then. In simplifying radical expressions, you only need to use absolute value to ensure that the expression cannot yield an invalid result if the radical index n is even (i.e., {2, 4, 6, …}) and: √ can be rewritten as: ( ) ( ) such that evenpower is less than the radical index n so that taking the root of ( ) will fully simplify the radical. {square root {-63}} / {square root 7}, Divide the radical expression.
