  • ОС Windows.
Run the program calculator. The appropriate link can be found in the main menu of the OS, but it is easier to press Win, type "ka" and press Enter - the system will understand you with two letters and open software calculator. For earlier versions of Windows, e.g. XP - this method can be replaced by pressing shortcut keys Win + R and input the command calc, then press Enter.
If the exponent of the root, which is required to compute equals two, immediately start the app, start typing number. This can be done either with the keyboard or by clicking on the buttons in the program interface. When you are finished, click the button with the image of a radical second from the top in the right column. The program will extract the root and display the result.
To calculate the cube root of the capabilities of the default startup interface is not enough, so activate more advanced "engineering." To do this, press Ctrl + 2 or select the corresponding item under "View" menu. Then enter the number, the root of which you want to calculate and click the button of the interface, marked by 3√x, and the task will be executed.
When extracting the root with the higher exponent, the input operation will consist of two steps. First, enter radical number, then click the button with the symbols ʸ√x, enter the exponent, and press Enter. The result will appear in the appropriate field of the application interface.
There is another method of extracting the root of arbitrary degree, which uses the operation of exponentiation with a fractional exponent. You know that root, for example, the fourth degree is equivalent to the power 1/4. Therefore, enter the number from which to extract the root, then click on the button of the construction to an arbitrary degree xʸ and type a decimal number corresponding to the unit divided by the exponent. For the fourth root is the number of 1/4=0,25. Press Enter, and the root will be extracted.
