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.

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)**

Put the calculator in the COMP mode. Use the ALPHA key to enter the X symbol in the square roots: ALPHA [)] to type X. Use the ALPHA key to type in the = sign (ALPHA CALC). Compose your expression

**Sqr(50*X)-Sqr(8*X)=1**

While the equation is still on the command line, press SHIFT CALC to (SOLVE).

You will see Solve for X.

Press the = sign at the bottom right. Wait for the solution to appear.

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

push 3

then push 2nd

then push the carot symbol ^ some calculators have this as y^x

then enter your number

If that fails use the calculator program in your computer and change its view to scientific. This has cube roots

then push 2nd

then push the carot symbol ^ some calculators have this as y^x

then enter your number

If that fails use the calculator program in your computer and change its view to scientific. This has cube roots

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.

I am guessing, but, find the key that has a 3 to the left of the root symbol, looks like a check mark. Push it, then the number you want to take a cube root of, then enter.

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....

Hello,

Here is how you enter it.

[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071

some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).

In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.

You can try

0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.
