Use the xth-root function. It's the shifted function of the y^x key, located just above the divide key. For example, to find the third root (cube root) of 64, press 6 4 2nd [xth-root] 3 =

### Simplify the square root of the fifth root of 64q^8v^6

Square root equivalent to power 1/2
Fifth root equivalent to power 1/5
square root of fifth root (if argument of square root is positive) is equivalent to power 1/10
64^(1/10)*q^(4/5)*v^(3/5)
using 64=2^6 you get 2^(3/5)*q^(4/5)*v^(3/5)

### I'm trying to find the cube root of 64 on my TI-30x ii s. I'm just trying to find out how to enter the root on the calculator

Enter the number 3 then hit 2nd button then the ^ button(cubed root), enter the number under the radical sign then enter.

### I need to know how to enter anything above cube root into my TI-83.

1. Use the universal power key marked with [^].
2. To avoid problems if the exponent is an expression, enclose it in parentheses.
3. To enter any power type number^(exponent)
4. If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
5. To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
6. Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

### Why does (-64)^(2/3) report an error 2?

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.

### How do you tak the square root of 64 or the 4 root of any other #

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

5. To extract the squqre root of a number you can use the key on the 3rd line [root x] or the general power key on line 6 with exponent 1/2
Exemple square root of 256
256 [Root x] [EXE] should give you 16
256 [Y to x] (1/2) [EXE] should give you 16 also

Hope that helps.
