Explicação passo-a-passo:

A)

$\frac{2.4 \times{10}^{ - 4} }{1.2 \times {10}^{2} } \Rightarrow\boxed{\boxed{2 \times {10}^{ - 6} }}$

B)

$(0.3 \times {10 }^{3}) \times (1.4 \times {10}^{2} )\Rightarrow0.42 \times { 10}^{5} \Rightarrow\boxed{\boxed{4.2 \times {10}^{4}}}$

C)

${(6.4 \times {10}^{4} )}^{2} \\ 40,96 \times { 10}^{8} \rightarrow\boxed{\boxed{4.096 \times {10 }^{9}}}$
