Answer 1

(b) =>4.0*10^4

(d) =>6.30032*10^6

Answer 2

$(6.4 \times {10}^{7} ) \div (1.6 \times {10}^{3} ) \\ ( \frac{64}{10} \times {10}^{7} ) \div ( \frac{16}{10} \times {10}^{3} ) \\ (64 \times {10}^{6} ) \div (16 \times {10}^{2} ) \\ ( {2}^{6} \times {10}^{6} ) \div ({2}^{4} \times {10}^{2} ) \\ \frac{ {2}^{6} \times {10}^{6} }{ {2}^{4} \times {10}^{2} } \\ {2}^{6 - 4} \times {10}^{6 - 2} \\ {2}^{2} \times {10}^{4} \\ 4 \times 10000 \\ 40000$
