Answer 1

a)

$\frac{(0,0003. {10}^{8}).(6000)}{(0,006. {10}^{15}).(2000. {10}^{5})} \\ \frac{3. {10}^{4}.\cancel6. {10}^{3} }{\cancel6. {10}^{12}.2. {10}^{8}} = \frac{3. {10}^{7} }{2. {10}^{20} } \\ = 1,5. {10}^{ - 13}$

b)

$\frac{(0,0035. {10}^{ - 4} ).(200. {10}^{6} )}{(700. {10}^{5} ).(0,00005)} \\ \frac{35.2. {10}^{8}}{7. {10}^{7} .5. {10}^{ - 5} }$

$\frac{\cancel35.2. {10}^{8}}{\cancel35 .{ {10}^{ 2} } } = 2. {10}^{6}$

c)

$\frac{(38000. {10}^{3}).(300. {10}^{ - 4} )}{0,00019. {10}^{ - 5} } \\ \frac{\cancel38. {10}^{6}.3. {10}^{ - 2}}{\cancel19 } =2. 3. {10}^{4} \\ = 6. {10}^{4}$

d)

$\frac{(3000. {10}^{ - 14} ).(0,0008)}{(0,0002. {10}^{5} ).(200000)} \\\frac{3. {10}^{ - 11} .8. {10}^{ - 4} }{2. 10 .2. {10}^{5} }$

$\frac{24. {10}^{ - 15} }{4. {10}^{6} } = 6. {10}^{ - 21}$
