Explanation:

Step1: Approximate 331,000,000 in scientific notation

331,000,000 is close to 300,000,000. In scientific notation, \(300,000,000 = 3\times10^{8}\). So 331,000,000 is approximately \(3\times10^{8}\).

Step2: Approximate 2,938,000 in scientific notation

2,938,000 is close to 3,000,000. In scientific notation, \(3,000,000 = 3\times10^{6}\). So 2,938,000 is approximately \(3\times10^{6}\).

Step3: Find how many times 331,000,000 is as large as 2,938,000

We can use the approximate values. \(\frac{3\times10^{8}}{3\times10^{6}}=\frac{10^{8}}{10^{6}} = 10^{2}=100\). So 331,000,000 is approximately 100 times as large as 2,938,000.

Answer:

331,000,000 is approximately \(3\times10^{8}\), and 2,938,000 is approximately \(3\times10^{6}\). So, 331,000,000 is approximately 100 times as large as 2,938,000.
