Question 204796
Do you mean you have trouble with simplifying them?  For example, if you want to simplify  


{{{sqrt(200)}}} you just have to think of perfect squares.  What do I mean?  Well.......


For example... you know that the {{{sqrt(100)}}} = 10 yes?
And you know that the {{{sqrt(25)}}} = 5 yes?
The above 2 examples are examples of perfect squares.  So let's go back to our problem.


When you have the {{{sqrt(200)}}} what is inside that number "200" that is a perfect square?   In other words, can you break down the number 200 into smaller numbers that would multiply together to equal 200?


What about the number 100?   


Think of {{{sqrt(200)}}} as {{{sqrt (100 * 2)}}}  Remember that  the {{{sqrt(100)}}} = 10, so just "pull" the 10 out of the square root sign and you have this:   10{{{sqrt(2)}}}


Is this the type of problem you are having?  How about if you post a problem or two and thennnnn you can get the step by step help you may need, k?
