Reciprocals, Squares, and Square Roots


The reciprocal ( x⁻¹ ), square ( x² ), and square root ( √x ) can be considered mathematically as raising a number to a predetermined power. Your calculator performs these functions in one keystroke. The functions are performed immediately and do not affect any pending operations.



Reciprocals

Use the [ 1/x ] key to calculate the reciprocal of any nonzero number in the display.

Squares

Use the [ x² ] key to calculate the square of a number in the display if the result is within the range of the calculator.

Square Roots

Use the [ √x ] key to determine the square root of a positive number in the display.

Example

This example illustrates the operation of the [ 1/x ], [ x² ], and [ √x ] functions.
