Powers, roots, and reciprocals
Keys
1. F squares the value.
2. b calculates the square root.
3. %c calculates the specified root (x) of
the value.
4. %a calculates the reciprocal.
5. G raises a value to a specified power.
Notes
• The examples on the transparency masters
assume all default settings.
•To use G, enter the base, press G, and then
enter the exponent.
• 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.
• The result of calculations with G must be
within the range of the TI-34 MultiView™
calculator.
• 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 (3

= 81.
• The base and the exponent may be either
positive or negative. Refer to Domain under
Error Messages in Appendix C for
restrictions.
• Use parentheses where needed to obtain the
desired results.
