Square root symbol - Casio FX-300MS Calculator

If, for example, you're getting the square root of 3 as the square root of 3, press the S-D button (just above the DEL) button to convert the symbolic result to a decimal result.

If you want all results to come up in decimal, press SHIFT SETUP 2 to select the LineIO mode.

x^2 squares the value (multiplies by itself), x^-1 inverts it (divides it into one), x! calculates the factorial, and square root calculates the square root.

You should be careful with the symbols you are using. Roots are different. When you say `5 square root symbol 1.734` you are in fact doing the following: 5x square root(1.734) which is 6.5850.
What you need to do is extract the fifth root of 1.734.
The key to use to extract a root of index n (in your case 5) is to press the digit key for the index, then press [2nd][Y^x]. On the calculator near the [y^x] key you can see xRoot. This is the universal root key.

The radical symbol is used to calculate square roots. It a radical has a small 3 to the top left of it, it means cubic root. It it has a a small n or a small x to the top left of it, it means nth root.

The way any of these roots works is one of the following:
Enter a number (positive for a square root or an nth root with n even) then press the square root button. The result is then displayed.

The other way is to press the root key then enter the number whose root you wan t calculate. The result is then displayed.

If you press the square root key and a radical is displayed withy a left parenthesis, you can be sure it is the second way.

On the leftmost side of your calculator, press the 2nd button.

Then, press the x^2 button (above it there should be a square root symbol)

Finally, type in the number you want to find the square root of

2ND [square-root] 2 0 =

The square-root is the shifted function of the multiply key. If the calculator shows you a symbolic result, press diamond ENTER to get a numeric result.

Use the square root key, marked with the symbol of a radical.
Press the [Radical] key followed by a positive number and press [=]
square root of 7: [Radical] 7 [=]

There is NO square root symbol on ANY pc keyboard ( unless its a specially made scientific numberpad integrated keyboard).
You will have to use the windows character map in you menu to find the symbol.

Don't forget to close the parentheses.

To compute the square root of 2, press SQRT 2 ) ENTER

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.
