You've got several different ways of doing this.

45235 ^ ( 1 / 7 ) ENTER

root(45235,7) ENTER

And, of course, you could always take the logarithm of 45235, divide it by 7, then take the antilog:

diamond e^x 2nd LN 45235 ) / 7 ) ENTER

If you get a symbolic result rather than a numeric one, press diamond ENTER.

Both LN and e^x are on the X key, just below HOME. You can access the root function through the catalog, the MATH menu, or simply spell it out.

Hi, how do i use casio fx82ms to raise a figure eg. to the power of 4?There's no xto the power of y button....


There should be key marked [Y to the x] or [^]. If exponent is negative use the change sign key (-) not the MINUS sign.You will have to use the [^] key if you calculate roots of order higher than 3. Example 7th root of 353 =(353)[^](1/7)

I can't find the universal power key or the universal root key on my TI-84 plus. Can someone tell me where it is?


The power key is marked ^ and is located just above the divide key. For example, to calculate 2 raised to the 7th power, press 2 ^ 7 ENTER

There is no key for the universal root. The operation is available in the MATH MATH menu. For example, to calculate the 7th root of 128, press 7 MATH 5 1 2 8 ENTER

I need to use the square root sign but I need to square root with 3, 4, and so on.


If you would like to a root other than a square root, first enter the root value (3, 4, 5, etc.) then press MATH. Then Press 5 and enter the value you want to take that root of. Press ENTER.

Please help me solve for g


Hello,
You want to isolate g, Ok. Start stripping it of all extraneous factors, by doing the inverse of each operation.
1. There is a 1355 multiplying the term with g: I divide by 1355 to get

(1+g)^7=20000/1355 = 14.7601476

2 The expression containing g is raised to the 7th power. So I do the inverse operation which is to extract the 7th root. If my previous result is still in [Ans] memory I write on my

(1+g) =[Ans][^](1/7) that gives 1.468970104

3. Now g is an expression that involves and addition. I perform a subtraction: I subtract the number 1. Assuming that my last result is still in [Ans] memory (I did not perform any other operation)

g=[Ans]-1 that gives 0.468970104

Hope you find this more instructive than just giving you the answer.

I need help with square root functions


Hello,
The square root has a dedicated key sequence [2nd][V square root symbol]
Square root of 21.2846 is entered [2nd][V square root] 21.2846 [ENTER] .
The result is`4.614.
I suspect you want to calculate the 4th root of 21.2846. If it is the case you enter that as
21.2846 [^](1/4) =2.148
Square root can be also entered as [^](1/2)
Cube root is entered as [^] (1/3)

..
nth root is entered as [^](1/n)
Hope it helps.

Basic Q's


The LOG and LN keys do what you have done.

To get 9 to the 16th power, enter 9, "y to the power x" (under the OFF key) then 16, then =

3 to the 12th power is the same, enter 3, y to the power x, 12, =, result 531,441

The inverse key sequence: value 1, 2nd, y to the power x, value 2, returns the xth root of y, e.g. 531,441, 2nd, y to the power x, 12, =, gives you 3 back

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.
