Powers, Radicals, and Reciprocals

F	Calculates the square of a value. The TI-34 MultiView™ calculator evaluates expressions entered with F from left to right in both Classic and MathPrint™ modes. Pressing 3 F F calculates as (32)2 = 81.
G	Raises a value to the power indicated. If you insert an expression as the exponent, you must place it between parentheses. In Classic mode, exponentiation using G is evaluated from left to right. The expression 2^3^2 is evaluated as (2^3)^2, with a result of 64. In MathPrint™ mode, exponentiation using G is evaluated from right to left. The expression 2^3^2 is evaluated as 2^(3^2), with the result of 512.
b	Calculates the square root of a positive value.
% c	Calculates the xth root of any positive value and any odd integer root of a negative value.
% a	Calculates the reciprocal of a value.
