9√2-3√7+√8-√√28
Factor 8 = 22 x 2. Rewrite the square root of the product √22 x 2 as the product of square roots √2² √2. Take V the square root of 2².
9√2-3√7+2√√/2 √28
Combine 9√2 and 2√2 to get 11√2.
11√2-3√7-√√28
Factor 28=2² x 7. Rewrite the square root of the product √22 × 7 as the product of square roots √22√7. Take the square root of 2².
11√2-3√7-2√7
Combine -3√7 and -2√7 to get -5√7.
So the answer then becomes 11√2 - 5√7 aka that first option.
Don't trust that first guy, he's only trying to get a brainliest from you.
