1. 3.6 × 10^3 + 7.3 × 10^4 =
2. 8 × 105 − 5.7 × 105 =

1. 7.66 x 10^4 (76,600)

2.  2.415 x 10^2 (241.5)

Step-by-step explanation:

1. First just do (3.6 x 10^3) and (7.3 x 10^4) to get 3600+73000 = 76600. In Scientific notation it would be 7.66 x 10^4

2. First do (8 x 105) and (5.7 x 105) to get 840-598.5 = 241.5. In Scientific notation it would be 2.415 x 10^2
