    Help using a Casio fx-83ES to calculate a fraction as an exponent.

    I am trying to teach myself algebra and I have downloaded a course book, but I arrived at the section for inputting algebra in to graphic calculators (I only own the Casio fx-83ES model) I have figured out some of the basics but I have arrived at :[e.g. 2x^2 + 3y^3 / (x+y)^1/2] could anyone please tell me how to (if at all possible) enter a fraction as the exponent (^1/2), I realise this is very basic but even the Casio user guide isn't very clear on this.

    Press the power button then enter the fraction in brackets.

    Help using a Casio fx-83ES to calculate a fraction as an exponent.-img00173-20120731-1150.jpg sorry for the terrible photo but this is what I am inputting in to the device, you can see the bracketed fraction shown as an exponent in the denominator. It is telling me there is a Math error when I try to get it to calculate. Thanks for the advice already and any in advance.

    Just download its manual from internet or consult with those who does it.

    I don't have the calculator, but note that (x+y)^{1/2} is defined only if x + y ≥ 0.
