how do you simplify radicals?

Question

anonymous · Answer

You take the number inside the root and split it up into numbers that can be "attacked" in a neater manner.
For example, $$\sqrt{12}$$ can be broken down into $$\sqrt{4} \times \sqrt{3}$$
The square root of 4 is equal to 2, so... $$\sqrt{12} = 2\sqrt{3}$$

Thank you. Do u know of a website that can help me with simplifying radicals or I can input the equations to simplify and check my work?

I'm pretty sure WolframAlpha can help you with that.
Otherwise, you could always use a calculator. You can plug in the original radical and see what decimal value it gives you, then plug in your simplified radical and see if it comes out as the same decimal value (because they should be equal.)
