Yes, I know that one cannot have negatives in even-indexed roots, but I somehow found myself dumb at answering for the odd-indexed roots. Nevermind, following the logic that only even-indexed roots cannot have negatives, I assumed that in the case of the odd-indexed roots negatives can be inside th...

Please, help me with this equation f(x) = sqrt[5](7x^2 - 12x). I need to find the domain of this function and indicate it in interval notation.

While I know how to find domain of f(x) = sqrt(7x^2 - 12x) I am struggling with the first function.
