Question

(8.2 x 10^4) + (9.7 x 10^5)

Answer 1

`\left(8.2\cdot \:10^4\right)+\left(9.7\cdot \:10^5\right)=1,052,000`

Explanation:

`\left(8.2\cdot \:10^4\right)+\left(9.7\cdot \:10^5\right)\\=8.2\cdot \:10^4+9.7\cdot \:10^5\\\\\rightarrow 10^4 = 10000\\= 8.2 \cdot 10000\\= 82000\\\rightarrow 10^5 = 100000\\= 9.7 \cdot 100000\\= 970000`

`970000 + 82000 = 1052000`
