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

### The initial population of a town is 2800, and it grows with a doubling time of 10 years. Whay wi the population be in 12 years

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.

### Please help me to use my TI - 84 so I can get a radical number when working with larger numbers. the steps I must take and having the TI - 84 set to the right function

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.

### How do you take the 3( square root) of 64 or the 4 root of any other number? im trying to take the 2nd button but still having trouble ? can u please help?

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.

### Cube how do I cube where is the function

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)

### Entering a cubed root into a ti-83 plus

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.

### I need some help please : )

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
