Taking the back off The Casio JF-100 calculator is similar to the ...TE. Remove the two screws at the top back. Place a small screwdriver blade along the seam where the back plate fits into the front plate. There are 3 fasteners on each long side and 1 fastener on each of the front and back sides. Find the spot where it's the easiest to separate the back plate from the top plate (there are only two). Carefully twist the blade to cause an opening.

Replace the battery. Press the front and back plates together to snap the fasteners.

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.
