Question: Find the absolute and percent relative uncertainty and express each answer with a reasonable number of significant figures. (a) 9.23 ( 0.03) + 4.21 (

Find the absolute and percent relative uncertainty and express each answer with a reasonable number of significant figures.
(a) 9.23 (± 0.03) + 4.21 (± 0.02) - 3.26 (± 0.06) = ?
(b) 91.3 (± 1.0) × 40.3 (± 0.2)/21.1 (± 0.2) = ?
(c) [4.97 (± 0.05) - 1.86 (± 0.01)]/21.1 (± 0.2) = ?
(d) 2.016 4 (± 0.000 8) + 1.233 ( ± 0.002) + 4.61 ( ± 0.01) = ?
(e) 2.0164 (± 0.000 8) × 103 + 1.233 (± 0.002) × 102 + 4.61 ( ± 0.01) × 101 = ?
(f) [3.14 ( ± 0.05)]1/3 = ?
(g) log[3.14 (± 0.05)] = ?
