Here are some properties you should know:

I understand the properties but how do you solve it.

If you understood the properties, I suspect you would not be having difficulties with the problem. By the way, we have nothing to "solve" here, this is not an equation. Rather, we are "simplifying" the expression.









Now, use the properties and to finish it:



As a final step, you may want to convert to radical form, depending on the problem's instructions.

You could actually apply the properties you say you understand or you could ask someone else to solve it for you. I see you chose the second solution method.
