Hello,
You do them the same way as you would for any exponent, except that you calculator has a limited capacity. If results exceeds 10^100 calculator gives an overflow error.
In case you are interested, the result is 6.75821x10^(176). That is clearly more than you calculator can handle. And don't go calculating n! for n larger or equal to 70.
Hope it helps.

How do i enter an exponent for ti-30xiis


Exponents of 10 are entered by pressing [2nd][X^-1] (EE).
For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

I am trying to calculate powers with my Texas Instruments BA ii plus, but big powers such as ^360 gives me an error msg. How can I solve this problem? Thanks!


Break the problem up into smaller pieces.

There's a limit to how big a number the calculator can represent. Numbers as large as 10 times 10 to the 100 simply can't fit into the calculator. For really large numbers, calculate the mantissa and the exponent (power) separately.

For example, to calculate 2^360, first calculate 2^300: press 2 ^ 3 0 0 = and see 2.037036*10^90. Divide by 10^90 (and remember the 90): / 1 0 y^x 9 0 = and see 2.04. Multiply by 2^60: * 2 ^ 6 0 = and see 2.348543*10^18. Multiply that by the 10^90 we took out earlier by adding exponents and write down 2.348543*10^108. That number is too large to fit into the calculator but we got it by calculating the 2.348543 and the 108 separately.

Trying to find the surface area of a sphere given the volume: V = 4/3 X pi X r cube problem given vol. find the surface area v = 5000 5000(3/4 pi =r cube the book reads: 3 cube before and the square...


Almost exactly the way it's written in the book.

In the LineIO mode press
3 SHIFT [xth-root] 5 0 0 0 * 3 / ( 4 * SHIFT [pi] ) ) =

In the MathIO mode press
SHIFT [xth-root] 3 right-arrow 5 0 0 0 * 3 / ( 4 * SHIFT [pi]) =

xth-root is the shifted function of the key just below and right of the big round cursor pad.
* is the multiply key
/ is the divide key
pi is the shifted function of the x10^x key in the middle of the bottom row

BTW there's no "square root" in this problem. There's a "cube root" or "third root". Square root is the second root.

I'm doing radicals I need to type an exponent into my calculator that goes before the square root not after. how do i do that (5) as an exponent square root of 32.....the answer is 2 but how do i type it...


Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

Want to know how to calculate a number raised to a power


Use the general power key marked with X to the y ( look for the image of a key on same line as Power in the screen capture)
You enter a number then press the power key and finally the exponent. If exponent is complicated (fraction, negative or other) enclose the exponent in parentheses.

You aslo have dedicated keys for certain powers and roots (square, square rooot, cube, cubic root)

I need to know how to enter anything above cube root into my TI-83.


  1. Use the universal power key marked with [^].
  2. To avoid problems if the exponent is an expression, enclose it in parentheses.
  3. To enter any power type number^(exponent)
  4. If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
  5. To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
  6. Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

Is it possible to calculate cube root or higher with BA ii plus?


To extract the roots of orders higher than 2, you can use the universal power key labeled as [Y to x]. if the exponent is an integer 3, 4, 5, 6 etc.
it gives the cube the 4th power, 5th, 6th, etc.
If the exponent is 1/3, 1/4, 1/5, 1/6 you calculate the cubic root, the 4th root and so on.
When you use it to calculate the roots, the radicand (the number the root of which you are calculating) must be positive, otherwise you may get the result as a complex number.

The syntax of the command is value [Y to x] (1/ order of root)

Ex: cube root of 27 is entered as 27 [Y to x] (1/3)

How to find cube root.


Hello,
What we call roots: square, cube ,fourth roots, etc. can be shown in algebra to be equiavlent to powers with fractionary exponents where numerator is 1 and denomonator an integer.
square root of a = a to the power 1/2
cube root of a = a to the power 1/3
n-th root of a = a raised to the power 1/n, n integer different from 0.

How to use calculator to calculate cube root?
If you do not have a specific (shortcut) key for it you use the key to raise to an arbitrary power [^ ], sometimes shown as [x^y]. The exponent will be 1/3. Do not replace 1/3 by its decimal approximate.

Cube root of 27 is entered as 27 [^ ] (1/3)

Hope it helps.

How to put a exponent on this calculater


Hello
To raise a number to an arbitrary power you use the [^] key below [CLEAR]

7.5 to power 4 is entered as follows
7.5 [^]4 [ENTER] gives 3164.0625

Other exemples (if you are interested)
Fifth root of 300 is enterd as 300[^](1/5) [ENTER]
If you raise a number to a negative power use the small minus sign (-)

157 to power of -3
157 [^][(-)]3 [ENTER] gives 2.584E-7 =2.584x10^(-7).

Hope it helps

I JUST GOT MY ti-8today and don't know how to use it


To do fractions, input like this:
(1/3)+(4/9)
Granted the answer is a decimal... But you should be able to convert that to a fraction using what you've learned in math class.

PI sign: Just press [2nd]and then[^]. And voila, instant π! Exponent:enter more complicated expressions involving exponents using parentheses and the negative sign.
