Solution 34594: Displaying Answers as Surd Numbers on the TI-84 Plus C Silver Edition Graphing Calculator.
Can I display answers as surd numbers on a TI-84 Plus C Silver Edition calculator?
The TI-84 Plus C Silver Edition graphing calculator cannot express answers in surd form. Answers on each device will be expressed in decimal form only.
Please Note: A surd is a number or quantity that cannot be expressed as the ratio of two integers. The term also refers to a symbol that is sometimes used to indicate that the number or quantity that follows it is a root. The surd symbol (nth root), all by itself, indicates the square root (1/2 power). If the surd has a number x written ahead of it and over the horizontal portion, then the symbol refers to the xth root (1/x power) of that number.
Please see the TI-84 Plus C Silver Edition guidebook for additional information.
