-24

$ 2 \sqrt 2 ( -2 \sqrt 32 + \sqrt 8 )$ We multiply the brackets using the distributive property. $ -4 \sqrt 64 + 2 \sqrt 16$ *** Take the square root of 64 which is 8. Because 8 x 8 = 64 *** Take the square root of 16 which is 4. Because 4 x 4 = 16 $ -4 (8) + 2 (4) $ $ -32 + 8 $ We add the numbers together -24
