Part 1:
Adding 1.95 ✕ 10^6 and 4.82 ✕ 10^12:
\(1.95 \times 10^6 + 4.82 \times 10^12 = 1.95 \times 10^6 + 0.00000000000482 \times 10^12 = 1.95 \times 10^6 + 482,000,000,000 = 482,001,950,000\)
Subtracting 8.03 ✕ 10^-8 from 3.2 ✕ 10^4:
\(3.2 \times 10^4 - 8.03 \times 10^{-8} = 32,000 - 0.0000000803 = 31,999.9999999197\)
Multiplying 2.56 ✕ 10^-2 and 4.82 ✕ 10^12:
\(2.56 \times 10^{-2} \times 4.82 \times 10^{12} = 0.0256 \times 482,000,000,000 = 12,371,200,000\)
Dividing 2.56 ✕ 10^-2 by 1.95 ✕ 10^6:
\(\frac{2.56 \times 10^{-2}}{1.95 \times 10^6} = \frac{0.0256}{1,950,000} = 0.0000000131282051282 \times 10^1 = 1.31282051282 \times 10^{-8}\)
Adding 4.82 ✕ 10^12 to 32.8:
\(4.82 \times 10^{12} + 32.8 = 482,000,000,000,032.8\)
Multiplying 3.2 ✕ 10^4 by 256.7:
\(3.2 \times 10^4 \times 256.7 = 32,000 \times 256.7 = 8,211,200\)
