Write each answer with the correct number of significant figures.
(a) 1.0 + 2.1 + 3.4 + 5.8 = 12.3000
(b) 106.9 - 31.4 = 75.5000
(c) 107.868 - (2.113 × 102)  (5.623 × 103) = 5 519.568
(d) (26.14/37.62) × 4.38 = 3.043 413
(e) (26.14/(37.62 × 108) × (4.38 × 10-2) = 3.043413 × 10-10
(f) (26.14/3.38) + 4.2 = 11.9337
(g) log(3.98 × 104) = 4.5999
(h) 10-6.31 = 4.897 79 × 10-7
