Hello,

I was wondering how to calculate a root, not specifically square or cube, on a Casio 25 E+ calculator.

Thank you for your help.

    Hello,

    A root is at least square by default unless otherwise specified that it should be nth…

    In this latter case, I'm not sure if there is an automatic function; we should always be able to calculate EXP(1/n) of x.

    If it's square, fourth link below your message.

      Hello again,

      thank you for your response. What I would like to do exactly is to calculate the fourth root of a number using this calculator.

      Thank you for these links, I'll check them out :)

        So even in the absence of a dedicated function, I just need to raise x to the power of 1/4.

        In this particular case, it's also sufficient to apply the SQR function twice in succession since SQR(x) = x to the power of 1/2 and SQR (x to the power of 1/2) = (x to the power of 1/2) to the power of 1/2 and thus x to the power of 1/4.
