How to multiply the root on the number

You decide school math problem. In the course of task execution was necessary to multiply the root on the number. You don't know how to do this, the root and the number seem to be completely different categories. Actually the root is the same number. Consider the problem on the example of a simple square root.

Instruction

1. Look at your root. If the numberrecorded under the root is a perfect square of another number (1, 4, 9, 16, 25, 36, 49, 64, 81, 100, ... ), remove the root. That is find such a whole number, the square of which is the numberrecorded under the root. Multiply it by the second multiplier. Write down the answer.
2. If the square root is not removed, then usually the answer can be recorded by simply removing the multiplication sign. It turns out the numberconsisting of an integer and a nearby root. This will mean that this root is taken such that an integer number of times. A whole number is usually written to the left of the root.
3. If you want all the number to enter under root, do the following. Construct the whole piece into a square. Comnote on the number, standing under a root. Note the resulting number under the root. This will be your answer.
