Answer: 2.622 x 10^14
==========================================
Work Shown:
(3.8 x 10^8)(6.9 x 10^5) = (3.8*6.9) x (10^8*10^5)
(3.8 x 10^8)(6.9 x 10^5) = 26.22 x 10^(8+5)
(3.8 x 10^8)(6.9 x 10^5) = 26.22 x 10^13
(3.8 x 10^8)(6.9 x 10^5) = (2.622*10^1) x 10^13
(3.8 x 10^8)(6.9 x 10^5) = 2.622 x (10^1*10^13)
(3.8 x 10^8)(6.9 x 10^5) = 2.622 x 10^(1+13)
(3.8 x 10^8)(6.9 x 10^5) = 2.622 x 10^14
