Exer. In evaluating negative numbers raised to fractional powers, it may be necessary to evaluate the root and integer power separately. For example, (−3)2/5 can be evaluated successfully as [(−3)1/5]2 or [(−3)2]1/5, whereas an error message might otherwise appear. Approximate the real-number expression to four decimal places.
(a) (−1.2)3/7
(b) (−5.08)7/3
