Question about Sharp Office Equipment & Supplies
Certain calculators such as the HP 48G are designed to return the complex principal root for any fractional exponent. Yours appanrently cannot handle complex roots, or is not in complex mode.
To get the real number root, compute the radicand first (-64)^2 using the x^2 key then compute the cube root using the cube root key, if there is one, or the general root key or even the general power key with exponent 1/3.
Hope it helps.
Thank you for using FixYa.
