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.

- 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). - 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)**

Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

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.

There's a cube root function in the MATH menu. As an example, to calculate the cube root of 125, press MATH 4 1 2 5 ENTER .

SQRT(81), here use the symbol that looks like a V, the radical

The other way is (81)^(1/2) where [^] is the general power key.

I come up with 3. (81^(1/2))^(1/2)=3. the Simplest form. I used 81^(1/2) because, 81 looks like 81 to the first power, instead of a fraction.

Hello,

Certain calculators such as the HP 48G are designed to return the complex principal root for any fractional exponent. Yours appanrently cannot handle complex roots, or is not in complex mode.

To get the real number root, compute the radicand first (-64)^2 using the**x^2**
key then compute the cube root using the cube root key, if there is one, or the general root key or even the general power key with exponent 1/3.

Hope it helps.

Thank you for using FixYa.

Hi shiny_diamon

Here is a picture of the powers and root functions of your calculator.

1.To calculate the cubic root of a number you use the key combination shown on line 5

Ex: Cubic root of 27

27 [2nd] [3 root x] [EXE]; Should get 3

2. You can use the general root key on line 7 [2nd][x Root y]

Ex: Cubic root of 125

125 [2nd][ x Root y] 3 [EXE] Should get 5

(-125) [2nd][x Root y] 3 [EXE]; Should get -5

3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3

Ex: cubic root of -125.

(-125) [Y to x]( 1/3) [EXE]; You should get -5

**4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.**

Ex: Fourth root of 256

256 [Y to x] (1/4) [EXE]: You should get 4

Hope that helps.
