## Kris5 2 years ago how do i subtract 2 radical 15 - 5 radical 2?

1. phi

depends what you are doing. You can write it as $2\sqrt{15}-5\sqrt{2}$ which is as simple as you can get it. However, you could use a calculator and change it to an (approximate) decimal number.

Ohh alright, then I'm probably doing something wrong on my math problem :/
