Dear student

a [- 10 - 3 \times \{4 - (- 4)\} \times \{3 - (5 - 3)\}] = [- 13 \times \{4 + 4\} \times \{3 - 2\}] = [- 13 \times 8 \times 1] = - 104

b 5 + 3 \{- 34 - 16 - 14\} \div 3 [17 + (- 3) \times 4 - 2 \times (- 7)] = 5 + 3 \{- 34 - 2\} \div 3 [17 - 12 + 14] = 5 + 3 \{- 36\} \div 3 [31 - 12] = 5 - 108 \div 57 = 5 - 1.89 = 3.11
