Answer:
472800 or 4.728x10^5
Step-by-step explanation:
first you would slove (4.7x10^5) and (2.8x 10^3). Which would be 470000 and 2800. Then add the two together to get 472800. And if they want you to put it back into scientific notation then it would be 4.728x10^5
Answer:
472800
= 4.728 × 10⁵
Step-by-step explanation:
(4.7 × 10⁵) + (2.8 × 10³)
4.7 × 10⁵ + 2.8 × 10³
(4.7 × 10²+ 2.8) × 10³
(4.7 × 100 + 2.8) × 1000
(470 + 2.8) × 1000
472.8 × 1000
= 472800
= 4.728 × 10⁵
