    Question Finding the value of Rational Indices

    It is just a simple revision, but the answer on the guide and my answers are different! So I would appreciate any help, thank you very much :] It would also be great if the method to solving is shown, because whatever I do, the answer is wrong so I wanted to check where I am wrong.(An example of a question too is given in order to get familiar with the question, just in sake. Thankyou)
    Eg:- Q. 82/3
    A. 8 2/3 = (23)2/3 = 2 3x2/3 = 22 = 4

    Math Question : 16-1/2
    My answer: 16-1/2 = 1/161/2 = 1/ √16 = 1/4
    Answer on the guide: 4

    I would appreciate any help, Thank you.

    Don't worry. You're right. The guide is wrong.
