Solution

Solution Steps

Step 1: Identify the Number to Round

The given number is $2.3390 \times 10^{8}$.

Step 2: Determine the Number of Significant Figures

We need to round the number to three significant figures.

Step 3: Perform the Rounding

The number $2.3390$ has five significant figures. To round it to three significant figures, we look at the fourth digit, which is 9. Since 9 is greater than 5, we round up the third digit (3) to 4.

Step 4: Write the Rounded Number in Scientific Notation

After rounding, the number becomes $2.34$. Since the original number was in scientific notation, we maintain the same power of ten: $2.34 \times 10^{8}$.

Final Answer

\[ \boxed{2.34 \times 10^{8}} \]
