What is 3 root 2 minus root 2?
Oh, what a happy little math problem we have here! When you have 3 times the square root of 2 minus 1 times the square root of 2, you can combine like terms. So, 3 root 2 minus root 2 is equal to 2 times the square root of 2. Just like that, we've created a beautiful, simplified expression.
How do you rationalize the denominator in this expression 2 divided by the square root of 3 plus the square root of 2?
Multiply everything by the square root of 3 minus the square root of 2 and then times that by 100 - 72 and divide that by 5
