Answer 2

Answer:

$\sf c.) \: \ 7.012 \times 10^{-8}$

Step-by-step explanation:

$\sf \rightarrow (3.012 \times 10^{-8}) + (4 \times 10^{-8})$

take out common factor

$\sf \rightarrow 10^{-8}(3.012 +4)$

add integers inside bracket

$\sf \rightarrow 10^{-8}(7.012 )$

in standard form

$\sf \rightarrow 7.012\times 10^{-8}$
