Question 14215: i don't understand roots, how do you simplify them?

You can put this solution on YOUR website!
For Example, sqrt%2850%29
If you type 50 and hit the squareroot button, it will give you a decimal, not a simplified root. In order to simplify sqrt%2850%29, you need two steps.
List all the factors and immidietly you will see 25%2A2=50.
The squareroot of 25 is what?
5!
Since you simplified the sqrt%2825%29=5, then you can take it out of the squareroot.
Then your number should look like this
5sqrt%282%29
Since there is no sqrt%282%29, this is your answer!
If it still could be simplified even more, you can calculate it and multiply it to the 5
