How do I make a square root sign on the keyboard?

Question

I'm suing an online graphing calculator and need to make a square root sign. Please help!

Answer 1

You can get the square root sign with the keyboard shortcut: Alt+251, ie: hold down alt, press (on the numpad) 2, then 5, then 1, then release alt. This produces '√' .

But note, it is unlikely that an online graphic calculator uses this. It might just be sqrt(...)

And if that does not work, square rooting is the same as raising to the 1/2 power, thus:

^(1/2) or ^.5 should work.

Answer 2

There isn't one on a regular keyboard. You can get the same result by raising a number to the correct exponent. If it's the square root, you raise it to 1/2. If it's the cube root, you raise to 1/3. For instance, the square root of 4 could be written as: 4^(1/2)

Answer 3

√ is available through Character Map. Go to Start, Accessories, System Tools, Character Map, and scroll down. You click it, click Select, and click Copy to copy it to the clipboard.

For most programs, "sqrt(X)" (without quotes, and with X as the number) should work. That is usually the command for a square root. I know for sure it works in JavaScript programming, and should work in most devices that use a normal keyboard input.

In Microsoft Word, you can set a keyboard shortcut for it (but the shortcut only works in Word). Go to Insert, Symbol... and in the top-right corner of the window, where it says "Subset," choose Mathematical Operators. The character should be the third row down, fifth symbol from the left. Click it, click "Shortcut key...," and on your keyboard, press the shortcut you want for it. A lot of them are taken (see "Currently assigned to:"), so you'll have to do some guess and check to find a shortcut not assigned to anything else. I recommend having the shortcut be something like Ctrl+9, 1, meaning hold Ctrl, press 9, release Ctrl, press 1. That way, you can make multiple symbols that start with the shortcut Ctrl+9.

Answer 4

keep in mind that the root of a function is a power
listed as a ratio,
(x)^(1/2) is the squareroot of x
(x)^(1/3) is the cuberoot of x
the thing to remember is the root taken is in the
denominator and the numerator tells you the if the function is to a power greater than 1
√(x^2) can be written
x^(2/2)=x^1=x
√(x^3)=x^(3/2)=x√x
I hope this helps
