Why won't my DateXX DS-883 Graphing Calculator work, it has new batteries?

Use the general power key [Y^x], [X^y] or [^] with an exponent equal to 1/5. N-th root is equivalent to ()^(1/N)

If you do not have an X_root key Use the general power key [Y^x], [X^y] or [^] with an exponent equal to 1/5. N-th root is equivalent to ()^(1/N)

You do not have to do anything special. Just enter what you want and press EXE. Depending on the display type chosen you get
2^20 EXE gives 1048576.000.. for floating point, 1.04857600 *10^06 for Scientific or the same (particular case here) 1.04857600 *10^06 for Engineering. The number of digits after the decimal mark depends on the number of decimal digits chosen in your setup.

If there is no dedicated key for this, but the calculator can calculate powers (ie x^y), then raise the number to the power 1/3 (or 0.333333333 etc).

Example 8^(1/3) = 2

In my opinion your calculator may suffer from the depleted battery syndrome. Certainly the first thing one should do is to replace the batteries with a fresh set. If the behavior persits then there is a problem.
There is no set value as to how long a battery should last. It all depends on the frequency and durarion of use.

Here is an example from the book. Page E-18

Calculate it the same way as on most other calculators, using the relation

log_b(x) = log(x)/log(b) = ln(x)/ln(b)

In words, calculate the log base 10 of x divided by the log base 10 of the base. You can also use the natural log function instead of the common (base 10) log--just be consistent.

Hello,
here is the link to your user guide for the Datexx DS-700-36
