If the number or expression you want to apply simultaneously, and the operation of root extraction, and the construction of its degree, bring both actions in a single - exponentiation with a fractional exponent. In the numerator of the fraction must be the exponent, and the denominator the root. For example, if you want to build in

**the square**of cubic**root**, then the two operations will be equivalent to one construction of the power⅔.2

If the conditions required to build in

**square****root**with exponent equal to two, this task is not the calculation, and to check your knowledge. Use method from the first step and you will get the fraction 2/2, i.e. 1. This means that the result of raising to**the square****the square**tion of the square root of any number is the number itself.3

If necessary, raised to

**a square****root**with an even exponent, it is always possible to simplify the operation. Since the two (the numerator of the fractional exponent) and any even number (the denominator) have a common divisor, then after simplification of the fraction in the numerator will be one and that means to involve in calculations, it is enough to extract**the root**with half the exponent. For example, in the construction of**the square**root, the sixth power of eight can be reduced to extracting from it a cube root, because 2/6=1/3.4

To calculate the result in all indicators of the degree of root use, for example, a calculator built into the Google search engine. This is perhaps the easiest method of payment you have access to the Internet from your computer. A common substitute symbol for the operation of exponentiation is that such a "lid": ^. Use it when typing in Google search query. For example, if you want to build in

**square****root**of the fifth degree from among 750, formulate the query: 750^(2/5). After entering the search without even clicking send to the server will show the result of calculations with the accuracy of seven decimal places: 750^(2 / 5) = 14,1261725.
