Change the output display to MathIO. You may be able to display square roots only: so no cube roots, nor fourth...

Press the Shift/Mode key and set the Input/Output to MathIO.

Even that will not guarantee that the display will be in root form. Only square roots are possible.

This calculator can show the results in radical form if it involves square roots. The 4th root of 243 is 3 times the fourth root of 3, which unfortunately is beyond the calculator's capabilities to display in radical form. Try taking the fourth root of 3 (or equivalently, the square root of the square root of 3) and you'll see the calculator display the result in decimal.

The capability of these calculators to handle irrational numbers in radical form is limited to square roots. Roots of index other than 2 are always displayed in their decimal representation.

If the calculator IO mode is set to MathIO, square roots will be displayed with the radical symbol. More complicated expressions with square roots might not be preserved and will be given as decimal numbers.

If you want the answer in rectangular form, set MODE a+bi and tap ENTER and QUIT. Tap square root sign, tap (-)4 and close the parenthesis and tap ENTER. The answer is shown as 2i.

If you want the answer in polar form, set MODE to re^xi and and DEGREE. Tap ENTER and QUIT. Tap the square root sign, tap (-)4, close the parenthesis, and tap ENTER. The answer shown is 2e^90i. (2 at ninety degrees). If you selected RADIAN mode, the answer would be 2e^1.57i (2 at 1.57 radians; or 2 at pi/2 radians)

The calculator cannot do that natively. There may be a program that you can drop onto your calculator to do it though.

has a ton of stuff... I saw two programs that sounded like it would do what you wanted... but I don't have an 85 to test it on so sorry if they don't...

Ones I saw are "**alghelp.zip" and "****algef85.zip"**
