29 - { 5 + 3 [ 8 × ( 10 - √64 ) ] - 50 }

My attempt:

29 - { 8 [ 8 × ( 2 ) ] - 50 } = [ 8 × 2 = 16 ] then { 8 × 16 = 128 - 50 = 78 } - 29 = 49

but the calculator says the answer is 126 and I don't know how it arrived at that solution. The textbook doesn't have the answer for this particular problem so I don't know where I went wrong. Please help. Thanks
