Can someone check my answer for: Simplify 11√8 +√12 - 5√2 I checked my answer on Wolfram and it says the answer is 17√2 + 12√3 But this is how I got my answer: 11√8 = √2 * 4 = √2 * √4 = 2√4 = 2√2 6√12 = √3 * 4 = √3 * √4 = 3√2 - 5√2 cannot be simplified anymore 11 + 6 - 5 = 12 √2 + √2 + √2 = √2 Combine everything: 12√2 Have I done something wrong, or do I have the right answer?
