You can put this solution on YOUR website!
Do you mean you have trouble with simplifying them? For example, if you want to simplify

sqrt%28200%29 you just have to think of perfect squares. What do I mean? Well.......

For example... you know that the sqrt%28100%29 = 10 yes?
And you know that the sqrt%2825%29 = 5 yes?
The above 2 examples are examples of perfect squares. So let's go back to our problem.

When you have the sqrt%28200%29 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%28200%29 as sqrt+%28100+%2A+2%29 Remember that the sqrt%28100%29 = 10, so just "pull" the 10 out of the square root sign and you have this: 10sqrt%282%29

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?
