Question

What is the sum of 3 x 10^6 and 4 x 10^6

Answer 1

`\begin{gathered} (3*10^{6^{}})+(4*10^6)^{} \\ \text{Let 10}^{6\text{ }}be\text{ x} \\ \text{That means} \\ 3x+4x \\ 7x \\ \text{Therefore, if 10}^{6\text{ }}=x,\text{ then 7x would be} \\ 7x=7*10^6 \\ 7x=7*1000000 \\ 7x=7000000 \\ \text{The sum of the two expressions is 7000,000} \end{gathered}`
