New Problems. Key fact – All radical expressions can be written with rational exponents. Here are some examples : Please write this down: If the n th root of a is a real number and m is an integer, then n n a a = 1 and ( ) m n n m n m a a a = = but if m is negative a can’t equal 0. Example: Convert each to radical form. a. 8 3 - a b. 4 . 0 v
