Thank you for the opportunity to help you with your question!

(2.52)(10^6) (6.5)(10^-7)  =  (2.52) (6.5 ) ) (10^6 * 10^-7)  =  16.38 (10^(6 - 7)) = 16.38 (10^-1) = 1.638


3.49 E^-4 = 3.49 * 10^-4 = 3.49 ( 0.0001) = 0.00349


8.67 E^-4  - 4.85 E^5  =  8.67 * 0.0001 - 4.85 * 100000 = 0.00867 - 485000 =  - 484999.9913


3.49 E-4 / 8.67 E-4 - 4.85 E5   =   0.00349 / -484999.9913 = -7.19587642 E-9


(2.52 E^6 ) ( 6.20 ) E ^6  =  (2.52 ) ( 6.2 ) ( 10^6) (10^6)  =  15.624 ( 10^(6+6)) = 15.624 (10^12) = 1.5624 (10^13) 

                                                                                                                                                         = 1.5624 E13


5.05 E4  = 5.05 (10^4)  = 50500


1.5624 E13 / 5.05 E4  =  1.5624/5.05 ( 10^13 - 4)  = 0.309 ( 10^9)  = 3.09 (E8)
