To calculate (8 \times 10^{10} + 4 \times 10^{9} + 7 \times 10^{5}), we first express each term in standard form: (8 \times 10^{10} = 80,000,000,000), (4 \times 10^{9} = 4,000,000,000), and (7 \times 10^{5} = 700,000). Adding these values together gives (80,000,000,000 + 4,000,000,000 + 700,000 = 84,007,000,000). In standard form, this is (8.4007 \times 10^{10}).
