To calculate a square root you press the square root key. A radical will be displayed. You type in the positive number whose root you want. Press the EXE key.

If your calculator is SetUp for Math Input/Output (MATHIO), a result that gives a radical will remain in radical form. If a radical appears in a denominator the whole expression is rationalized: Any radical left is put in the numerator. 1/Sqr(3) is displayed as Sqr(3)/3.
