Ex. for 5^3, press 5, then "yx" (beneath "OFF" button), then the power (3), then press =... 5 --> yx --> 3 --> = --> 125. Hope this helps!

The carrot key (exponent key) is on the very first column from left to right. It is the 5th key on the row from bottom up or top to bottom. Both will give you the same key. Try it. Type 2^3 it should give you 8.

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)

How to i raise e to a power


That is the exponential function. Look for a key marked [LN] (the natural logarithm). The exponential function e^(x) shares the same physical key as the natural logarithm.
You access one function directly (marking on surface of key) and the other with [2nd] LN

I'm going to assume you want to raise a number to the 4th power.

One way is to square it twice. Another is to use the ^ key located just above the divide key. For example, to raise 2 to the 4th power, press
2 ^ 4 ENTER

When I try to get an exponential of a number by pressing eex I get figure 1 and some 00 at the end of the right corner


The EEX key is used to enter the exponent of a power of 10. To raise e (the base of natural logarithms) to a power (exponentiation) press [g][e^x]: You enter a number (the exponent) then [g][e^x] and the result will be displayed.

How do I do an inverse log function on my HP 33s calculator?


The inverse of the common log is the raise 10 to a power. the inverse of the natural log is the exponential. The log and the antilog share the same key, one is accessed directly the other as a seconf/shifted function. Same thing for the natural log (ln) and the exponential.
