To calculate

**the root of****the third***degree*, use the calculator. It is desirable that it was not a normal calculator, and the calculator used for engineering calculations. However, even with such a calculator, you will not find a special button to retrieve the root of**the third***degree*. So use the function to raise a number to a power. The root**of the third***degree*corresponds to the power of 1/3 (one third).2

To raise a number to the power 1/3 type on the keyboard of the calculator itself. Then press the "exponentiation". This button, depending on the type of calculator may look like xy (in Superscript). Since most calculators there is no possibility to work with conventional (non-decimal) fractions, instead of the number 1/3 type it the approximate value of 0.33. To obtain greater precision, it is necessary to increase the number of "triples", for example, to get 0,33333333333333. Then, click the "=".

To calculate

**the root of****the third***degree*on the computer, use the standard Windows calculator. The procedure is completely similar to that described in the previous paragraph instructions. The only difference is the name of the exponentiation. "Computer," the calculator, it looks like x^y.4

If

**the root of****the third***degree*have to be considered systematically, use the program MS Excel. To calculate**the root of****a third***degree*"Excel", type in any cell " = " sign and then select the "fx" insert function. In the appeared window in the list, Select " select "DEGREE." Click "OK". In the newly appeared window enter the string "Number" value, from which to extract**the root**. In the line "Amount," enter the number "1/3" and click "OK". In the cell the table shows the value of the cubic root of the original number.
