When I enter square root 36 equals syn error; 36 square root equals syn error what am I doing wrong? Deb

Hello,

You should enter it as follows [SQRT]36 ) [ENTER/=].

If you define some function f of a variable x you write that f(x), where the parentheses enclose the so-called argument (objet on wich the function acts). It seems that on this calculator the opening parenthesis is implicit: the calculator supplies it when you press [SQRT] but does not display it (a design flaw?). However the closing parenthesis must be entered by you to signifie to the function [SQRT] that you have finished entering the argument. Weird but one can live with it.

Hope it helps.

Two ways the calculator may work:

Enter a positive number then press the square root key, or

Press the square root key then type in a positive number and press =.

Enter a positive number then press the square root key, or

Press the square root key then type in a positive number and press =.

We are asking what number, times itself, is equal to 30. Five times itself is 25. Six times itself is 36. The answer is somewhere between 5 and 6. Let's split the difference and try 5.5. 5.5 times 5.5 is 30.25. This is above 30, so let's try a smaller number, 5.4. 5.4 times 5.4 is 29.16. This is lower than 30, so we need a higher number. How about 5.45? I get 29.7025. We need a number a little higher. How about 5.47? I get 29.9209. Still need a little higher. How about 5.48? 30.0304. So it is somewhere between 5.47 and 5.48.

On a calculator, you can use the square root function. Sometimes you have to enter the number before you hit the square root function and sometimes you need to enter the number after hitting the square root function. Another way of doing it is to use the exponent function, usually with a y to the x key or a ^ key. Enter 30, hit the exponent key, and then enter 1 divided by 2 in brackets.

I get approximately 5.477225575051661134569697828008.

Good luck.

Use the xth-root function in the MATH menu (it should be the fifth item). For example, to calculate the 15th root of 2, press 1 5 MATH 5 2 ENTER .

Yes, your Ti 86 should solve square root problems. At the HOME screen press [CLEAR] [2nd] [x^2] which gives the (Square Root Symbol) to display at the Home screen. Then enter the number you want the square root of and close the bracket [ ) ] and, press the [ENTER] key.

You can even get the square root of complex numbers too. Select the correct complex format in the mode settings. For example: I'll do one in the rectangular form by enter a number as (a, b). I then will go to [2nd] [MODE] then [Arrow down] 3 times and make sure the RectC is highlighted and selected. Then quit out of the mode settings screen and enter [CLEAR] [2nd] [x^2] [ ( ] [9] [ , ] [ - ] [4] [ ) ] [ ) ] [ENTER], this displays the SQRT((9,-4)) equals (3, 2); The real part is 3 and the imaginary part 2.

Hi,

There is a dedicated key for the function. The key is labeled as on the third line of the table below. You enter a positive number, press the key and then hit [=]. Hope it helps.

Hello,

Use the square root key accessed after pressing the [2nd] function key.

Press**[2nd] [Square root key] 121 [ ) ] [ENTER]**. Do not forget the right parenthesis, even if you did not have to enter the left parenthesis.

The result should be 11 (one of the square roots to remember).

Hope it helps.

A squared + B squared = C squared

15 squared + 15 squared = C Squared

225 + 225 = c squared

450 = c squared

the square root of 450 is 21.21320433

15 squared + 15 squared = C Squared

225 + 225 = c squared

450 = c squared

the square root of 450 is 21.21320433
