Question 14215
For Example, {{{sqrt(50)}}}
If you type 50 and hit the squareroot button, it will give you a decimal, not a simplified root.  In order to simplify {{{sqrt(50)}}}, you need two steps. 
List all the factors and immidietly you will see {{{25*2=50}}}. 
The squareroot of 25 is what? 
5!
Since you simplified the {{{sqrt(25)=5}}}, then you can take it out of the squareroot.  
Then your number should look like this
{{{5sqrt(2)}}}
Since there is no {{{sqrt(2)}}}, this is your answer! 
If it still could be simplified even more, you can calculate it and multiply it to the 5
