a)
[tex](6 \times {10}^{7} ) \times (3 \times {10}^{2} ) = 18 \times {10}^{9 =} = \\ = 1.8 \times {10}^{10} [/tex]
[tex] \frac{6 \times {10}^{7} }{3 \times 10 {}^{2} } = 2 \times {10}^{5} [/tex]
b)
[tex](7 \times {10}^{8} ) \times (5 \times {10}^{3} ) = 35 \times {10}^{11} = \\ = 3.5 \times {10}^{12} [/tex]
[tex] \frac{7 \times {10}^{8} }{ 5 \times {10}^{3} } = \frac{7}{5} \times {10}^{5} = 1.4 \times 10 {}^{5} [/tex]
c)
[tex]1.6 \times {10}^{9} \times 4 \times {10}^{5} = 6.4 \times {10}^{14} [/tex]
[tex] \frac{1.6 \times {10}^{9} }{4 \times {10}^{5} } = 0.4 \times {10}^{5 } = 4 \times 10 {}^{6} [/tex]
