    is this (4)^1/3 or 2^1/3 * 2^1/3 = 4^2/3

    Is 1/3 the exponent? or is it a 2?

    1/3 is the exponent

    Always remember PEMDAS. Parentheses before exponents. So (4)^1/3

    but then why is this true: (xy)n = x^ny^n

    \[(xy)^{n} = x ^{n} y ^{n}\]

    It says this in a book or something, correct?

    i thought the same thing- PEMDAS, but yet that changes the answer...i think.

    This is because the exponent is a variable which distributes into the parentheses.

    i see- with numbers you actually solve and with variables you can't, so you distribute?
