Answer:
10 ( 12913 ) or 12913 * 10^1
Step-by-step explanation:
(1.28 x 10^5) + (1.13 x 10^3)
--------------------------------------------
1.28 = 128/100 = 128/10^2
1.13 = 113/100 = 113/10^2
-------------------------------------------
(128/10^2 * 10^5) + (113/10^2 * 10^3) <---- 10^5/10^2 = 10^3
(128 * 10^3) + (113 * 10^1)
10^1 ( 128 * 10^2 + 113)
10^1 ( 12800 + 113)
10 ( 12913 )
