Set the radical number a>=0, from which is extracted

**the root**. Suppose for example a=8. Also referred to as the number standing under the root sign.2

Write the integer n1. It is called the index of the root. If n=2, we are talking about the square root of a number. If n=3,

**the root**is called cubic. For example, let us take n=6.3

Select an integer k —

**the degree**in which it is necessary to erect**root**. Let k=2.4

Specify the resulting solution for example. In this case, you have to square

**root**to the sixth power of the number eight.5

To solve the problem erect in

**the degree of**radical number: 82=64.6

Formulate the resulting problem: now you need to extract

**the root of**the sixth power of the number 64.7

Convert radical expression: 64=8*8, i.e. it is necessary to extract

**the root of**the sixth power of two multipliers. Otherwise can be written as:**the root of**the sixth power of eight multiplied by**the root of**the sixth power of the number eight. Another option the recording:**the root of**the sixth power of the number eight in the square.8

Another transform used in the example: 6=3*2. Now square — number two — is in radical expression and exponent. Therefore, they can be mutually reduced, then an example will be,

**the root**of the third degree of the number eight. Cubic**root**of eight equals two is the answer.9

To build

**the root**in**the degree**in another way, after the fourth step of the transform from n=6=3*2. Number two is in degree, and in the figure of the root, so the two can be reduced.10

Write down the transformed problem: find

**the root**of the third degree of the number eight. With the radicals did not have to do anything, because the sample is immediately simplified. The answer is two cubic**root**of eight.
