Question

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?

Answer 1

Now that I see it, I found I did something wrong!
