Question about Texas Instruments TI-30XA Calculator

Using

Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....

I need help! I have a TI-30x calculator and theres no button for the square root. Theres the sign under a button, but cant find out how to work it! Anyone know?

SOURCE: ok im using the Ti 30xa how do i find the square

1. Type in the number you wish to find the square root of.

2. Press the square root button. It is located to the immediate left of the divide button.

SOURCE: Finding a cube root on calculator

You can calculate cube roots by using the cube root function (the 2nd-shift of the 0 key). You can calculate arbitrary roots by using the x-root function (the 2nd-shift of the y^x key, just above the divide key).

SOURCE: My TI-89 will not calculate the square root of 3

Press the diamond key, then press ENTER to convert a symbolic result to a decimal result. If you want them all in decimal form, press MODE then F2. Scroll down to Exact/Approx and change that setting to Approximate.

SOURCE: I need the EXACT solution

It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2

or

b: ((SQRT61) / 2) - 7

For a:

Type 61 SQRT.

Subtract 7.

Equals.

Divide by 2.

Equals. (Should be 0.4051248...)

For b:

Type 61 then SQRT.

Then divide by 2.

Equals.

Then subtract 7.

Equals. (Should be -3.094875...)

Good luck.

SOURCE: Now that I know where

You don't want the square root. In this example, you want the sixth root.

Press 4 5 2nd [xth-root] 6 =

The xth-root is the shifted function of the y^x key, located just above the divide key.

1and 5/7 ==1.7142 (5/7 to get decimal point=.7142)

+ 9 divided by minus 1.7142= minus 5.1688

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0.345 345 345 ... =345/999=115/333

With algebra you are learning problem solving-that is the process of problem solving using rules and equations. The best way to learn it is to shut out all distraction and work at it. If there is something you don't understand you may have to go back to the beginning and learn all the principals and rules that you don't understand- Algebra can be a very hard subject but it can be concord with persistence.

454 grammes to a pound ,use the calculator in the computer but roughly that 1cwt or 100 pounds divided by 14 ,which is 14 pounds to one stone ,wow this takes me back to pre decimalisation

Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
