Answer 2

Answer:

$\sf 9.013*10^{-8}$

Step-by-step explanation:

Use Distributive property: a*c + a*b = a*(b +c).

$\sf 10^{-8} \ is \ common \ in \ both \ the \ terms. \\\\7.013*10^{-8} + 2 * 10^{-8} = (7.013 + 2) *10^{-8}$

Now, add 7.013 and 2.

                                   $\sf = 9.013*10^{-8}$
