SOURCE: HOW TO FIND CUBE ROOT

There is a way to do it. I believe you go into "complex" or "math" buttons. These buttons are yellow on the calculator. Therefore, to access them you must hit "2nd" then the button.

Better yet, you can also get around this dilemma another way. You can enter "the cubed root of x" by raising x to 1/3.

For example the cubed root of x = x^(1/3). It is best to place parentheses around 1/3 so the calculator knows exactly what you mean.

Another example, the "cubed root of (x + 1)" can be entered by:

(x+1)^(1/3) Note the parenteses around both (x+1) and (1/3). This applies if the radical cover both "x" and "1".

Hope this helps.

SOURCE: Cube roots

You use the y^x (y to the x) key along with the 2nd function key. That does the opposite operation.

So, let's pick something we know the answer to as an example. How about the cube root of 8? We know 8 = 2 X 2 X 2, so the cube root of 8 will be 2.

Here's how:

8 2nd y^x 3 =

The display will show 2.

The three is the root you want. You can put in any number, with 2 being the square root, 3 the cube root, etc.

SOURCE: How do I calculate the square root of a number on

enter the number, press 2nd and then press the button that has the squareroot and the x in the middle (beside the AC/ON button) for example, i have to find the square root of 25, i press 2nd and the button and i get 5, hoped this would help :-)

SOURCE: How do you use the imaginary number with the TI-84 calculator?

If you want the answer in rectangular form, set MODE a+bi and tap ENTER and QUIT. Tap square root sign, tap (-)4 and close the parenthesis and tap ENTER. The answer is shown as 2i.

If you want the answer in polar form, set MODE to re^xi and and DEGREE. Tap ENTER and QUIT. Tap the square root sign, tap (-)4, close the parenthesis, and tap ENTER. The answer shown is 2e^90i. (2 at ninety degrees). If you selected RADIAN mode, the answer would be 2e^1.57i (2 at 1.57 radians; or 2 at pi/2 radians)

Use the root function in the MATH MISC menu.

To find the 5th root of 32: enter 5 then the root function and then 32 and then ENTER to get 2.

Testimonial: *"Thank you!"*

If you are concerned about fraction handling and conversion to decimal representation, upgrade the OS of your calculator to 2.5x MP. As to handling of irrational numbers (such as square roots) you should visit the TIcalc.org website to look for any 3rd-party program that can do that.

You can use the SHIFTED [^] key (Xroot) . Enter the index of the root (4, 5, 6, nth), press [SHIFT][^] then the radicand.

You can also use the fact that nth-root is equivalent to a power (1/n)

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

In the MATH MISC menu you'll find the xth-root function. Use this to find the 3rd root.

3 xth-root 8 ENTER will give 2.

3 xth-root 8 ENTER will give 2.

No such function my ***!

Just click prb --> RAND randint(

If you want a random integer from 1 to ten, randint(1,10

Then you just keep clicking enter to get different numbers.

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.

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.

You can multiply a number by 1/3rd to get the cube root or

Under the MATH button, the fourth option down will give you cube root. Any n root beyond that will require the x^(1/n) method.
