Explanation:

Step1: Recall scientific - notation rule

Scientific notation is of the form $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Convert 980,000 to scientific notation

Move the decimal point 5 places to the left to get $a = 9.8$ and $n = 5$. So, $980000=9.8\times10^{5}$.

Step3: Convert 7,436,100 to scientific notation

Move the decimal point 6 places to the left to get $a = 7.4361$ and $n = 6$. So, $7436100 = 7.4361\times10^{6}$.

Answer:
