Question about Texas Instruments TI-84 Plus Calculator

Use the universal power key marked [Y to x] or [Y^x].

This key allows you to calculate powers with arbitrary exponents.

To obtain the roots to any degree you make use of the fact that n-th root of a number X is equivalent to the number X raised to the power 1/n

10th root of X = X raised to the power 1/10

10 th root of 2345 = (2345)^ (0.1)

For this case

2345^(0.1)=2.172772644

Press 2nd then F--D key(its means left arrow key or left key from zero)

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

The population doubles in ten years so the annual growth is the tenth root of two. The growth in twelve years is the annual growth rate raised to the twelfth power.

The tenth root of two is about 1.0718 . That value raised to the twelfth power is about 2.2974 . Multiplied by the initial population of 2800 gives 6433.

On the TI-30XA press 2 2nd [xth-root] 1 0 = y^x 1 2 * 2 8 0 0 =

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 =

I am afraid I do not completely understand what you want. This calculator does not have a Computer Algebra System or CAS. So the results of all calculations will be displayed as decimal numbers, and that includes the square and other roots that are irrational numbers (square root of 2, 3, 5 7, etc.)

You cannot manipulate radicals on this calculator, whether for small numbers or large numbers. Sorry.

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.

Press 4 then press math. Select #5. You'll be back at the home screen now type 90 and press enter. You can use this for any root.

x-th root of a number equals the number to the power of (1/x) where x is a natural number.

square root = to the power of (1/2)

cubic root = to the power of (1/3)

square root = to the power of (1/2)

cubic root = to the power of (1/3)

You can enter any root by typing the number, then hitting MATH and 5, which brings up the root symbol with the x in front of it: x√. So the fifth-root would be 5 -> MATH -> 5 and then whatever number you want to get the fifth-root for: 5x√10 for example. As someone else had mentioned, you can also raise it to a rational power: 3^(1/3) which would be the same as the cubed root of 3, but you could also type: 3 -> MATH -> 5 -> 3 and get the same answer, but looking like this in your calculator: 3x√3. The option for 4 actually is a predefined cubed-root, and the one for option 5 there is the root symbol that can be used with any number before it to get any root you want. There are no parenthesis as you get when using the predefined square-root and cubed-root functions, though, so you may want to type them in yourself if entering a long string of operations in the calculator at one time to make sure the calculator doesn't include numbers under the root that you don't want it to. But I guess it depends on preference in terms of what method you choose between the rational exponents or the root symbol (and most would go with whichever seems easiest and quickest to enter), but you asked specifically how to get the cubed-root on the TI-83 Plus, so there's my best attempt at answering your question.

The parenthesis is there so u can put a number under the radicle. Just close the parenththesis once u put the number under the radicle
