Finding the 4th root on a ti30xs calculaltor - Texas Instruments TI-30XA 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)

This calculator can show the results in radical form if it involves square roots. The 4th root of 243 is 3 times the fourth root of 3, which unfortunately is beyond the calculator's capabilities to display in radical form. Try taking the fourth root of 3 (or equivalently, the square root of the square root of 3) and you'll see the calculator display the result in decimal.

4th root of 93 = 3.1054228
Break it down like this: 4th root is the same as sqrt (sqrt 93)

sqrt of 81 is 9.
sqrt of 9 is 3, so you know the answer is 3....

To get the most precise answer, use a calculator and take the sqrt of 93, then take the sqrt of the answer.

Hi there,To find the cube root, you need to press 3, then press the 2nd key, then press the ^ key (4th below the 2nd key), then press the number you want to cube root.
Cheers,Alex

Use the x-root function, which is the 2nd function of the y^x key located just above the divide key. For example, to find the cube root of 8, press 8 2nd x-root 3 =

You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).

To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.
it gives the cube the 4th power, 5th, 6th, etc.
If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.
When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

Hello,
There is a relation between roots and fractionary powers.

2nd root (square root) of X = X^(1/2) power 1/2
3rd root (cubic root) of X = X^(1/3) power 1/3
4th root of X = X^(1/4)
...
n-th root of X = X^(1/n)

Use the raise to arbitrary power key labeled as a caret [^] or [X to the y] or [Y to the x]
Hope it helps.

If you want to take the nth root, enter the root first then press math 5 and then the number you are trying to take the root of.  For example to take the 4th root of 1000, press 4, math, 5, 1000, enter.
