### How do I find the 4th square root of 16 on a datexx ds-700 scientific calculator??

Roots are called as follows:

square root

cube /cubic root

From 4th on, use the ordinal fifth, sixth, ... n-th

To calculate the fourth root you have two possibilities.

1. Some calculators have the x-root key marked with an x followed by the radical symbol. See the screen capture on how to find your result.

Usually the x-root is the SHIFTED function of the general power key that is marked ( [^], [X^y], or [Y^x] ). To use it, you inter the index of the root (the ordinal number). then you press the [SHIFT/2nd/ 2nd] [X^y] sequence and the number whose root you are calculating).

2. Alternatively: Use the equivalence n-th Root (x)=x^(1/n), meaning that to extract the fourth root of 16, you raise 16 to the power of (1/4)

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

Try a Q-Tip soaked with alcohol and clean the battery terminals. Also, WD-40 works well to. If batteries are left in too long after a total discharge, it can produce acid which will eat away the plating on the terminals. If that's the problem, WD-40 is the best choice to use.

### I have a DATEXX DRC-605 Exactime clock that just changed the date to two days ahead for some reason. How can I change it back to correct date?

* Press and hold MODE button for 3 seconds: the year digit will flash.

* After the first value is set, press MODE button again to confirm and move to the next parameter.
* Continue setting month, date, hour, minutes and temperature display format.
* Press MODE button for the last time to return to the time of day with seconds, after the last parameter is set.

I hope I could help.
Thanks.

### How do i do log base x problems (other than log base 10) on the datexx ds 883?

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.
