What do i push to find the square root of a number

On a TI 36X Solar, you enter the number and press the square-root key.

If you're asking about some other calculator, please reply to this post and specify the make and model of the calculator.

The square root is the second function of the "3" key. To calculate the square root of 3, press 3 2ndF 3 =

Take the fourth root. The square root, denoted by a 2 on top of the "root thing" or more commonly without a number at all, is the second root.

Usually the easiest way to calculate the fourth root is to calculate the square root of the square root. So in this case the fourth root of 81 is the square root of the square root of 81. The square root of 81 is 9, the square root of 9 is 3.

You can use the square-root function for any number, whether it's a perfect square or not. For example, to calculate the square root of 2, press SHIFT [square-root] 2 EXE .

[square-root] is on the x^2 key, just to the right of the ALPHA key.

Press 2nd [square-root], enter the number, press ) =

For example, to calculate the square root of 5, press 2nd [square-root] 5 ) =

To calculate the square root of 9, press
2nd [square-root] 9 ) =

The square-root is the shifted function of the x-squared key, just to the left of the 7 key. The close-parenthesis is needed to balance the open-parenthesis automatically inserted by the square-root function.

The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

Two buttons under the shift key-(top left key) and to the right one is the square root key. Just push it and put the number in...it is not manditory to close the parentesis. You can also hit shift before the square root key to get the cubed root.

Use the toggle button above the enter key. It looks like 2 arrows

thanks it workd
