    Which of the following is equal to 8 1/3( equavalent to 2 in decimal form)?

    A) 7^(3/3) ( which is equal to 7)
    B) 7^(4/3) ( which is equal to 13.39)
    C) 7^(5/8) (which is equal to 3.37)
    D) 8^(3/3) (which is equal to 8)

    8 1/3 = 8 + 0.33 = 8.33
    7 4/3 = 7 + 1.33 = 8.33

    I understand now. For future references "^" means to the power of, therefore

    7(4/3) is not the same as 7^(4/3). That is saying "seven raised to the power of 4/3" which would give you a totally different answer.
