I am needing to find out what key I can push for an exponent. I have an exponent that is 2520 and I dont know what button to push for it.

The problem is as follows:

3000 ( 1+ 0.06/360) exp.2520

3000 ( 1.000166667) exp. 2520

3000 - 4565.72

1565.72

Now how in the world did they get 4565.72. What buttons am I needing to push.

ok so when you're typing it into your calc. like that don't type it in without parenthesis.

example:

2^3=8
to find the cube root of 8, you type in 8^(1/3)

DONT type 8^1/3 because that means that you raising the 8 by a one and then dividing that answer by 3

SOURCE: nth root button on it89

Hello,
There is no nth root button per se. But to take the nth root of a number is equivalent to raising the number to the power 1/n

Nth root of X= X^ (1/n)
Hope it helps.

### HOW TO FIND CUBE ROOT OF A NUMBER ON fx-82ms

There are several ways to find the cube root of a number on a calculator. On this calculator, we can use the nth root button, by using the yellow shift button with the ^ key. Another way to do this is just to use the ^ key.

For example, the cube root of 8 is performed by the following key sequence: 8, shift, ^, 3.

Another sequence is: 8 ^ (1/3)

Good luck.

Paul ### Compute the nth root

The nth-root function is the right-shifted function of the square-root key, second column from the left, fifth row from the top.

In RPL mode, to calculate the third root of eight, press 8 ENTER 3 right-shift [nth-root] and get 2.

In algebraic mode, press right-shift [nth-root] 3 right-shift [,] 8 ENTER and get 2. (The comma is the right-shifted function of the SPC key on the bottom row.)

### How do i use the radical symbol on my ti-30xs

The radical symbol is used to calculate square roots. It a radical has a small 3 to the top left of it, it means cubic root. It it has a a small n or a small x to the top left of it, it means nth root.

The way any of these roots works is one of the following:
Enter a number (positive for a square root or an nth root with n even) then press the square root button. The result is then displayed.

The other way is to press the root key then enter the number whose root you wan t calculate. The result is then displayed.

If you press the square root key and a radical is displayed withy a left parenthesis, you can be sure it is the second way.

### HOW do I get the sixth root of 63717646

Not knowing the model of calculator you have I cannot say USE the Xroot key. But you can still use the general power key [^] if you remember that an n-th order root is equivalent to a power of 1/n
If the order of the root (n) is even you cannot use a negative radicand. The result is generally a complex number

nth root of ( 63717646)= ( 63717646)^(1/n)
6th root of ( 63717646) =( 63717646)[^¨] (1/6)
The result should around 19.98526696

### How can I find the square root of 39 on my ti-30xa? Also I would like to know how to find the cube of 9482... Help

Square root of 39: Press 3 9 [square-root] =
[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =
[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

### Nth roots

Use the nth-root function, which is the shifted function of the y^x key just above the divide key. For example, to calculate the 5th root of 32, press 32 2nd [xth-root] 5 =

### Cube roots or higher

If you want to take the nth root, enter the root first then press math 5 and then the number you are trying to take the root of.  For example to take the 4th root of 1000, press 4, math, 5, 1000, enter.
