Most Upvoted Answer
Round the following answers so that significant digit appears 1. Log3*...

Round the following answers:

1. Logarithmic Calculation
- Log3*10^-3 = -5.5228787
- Rounded to one significant digit: -5.5

2. Antilogarithmic Calculation
- antilog13.8 = 6.309573*10^13
- Rounded to one significant digit: 6.3*10^13

Explanation:
When rounding to one significant digit, we look at the first non-zero digit from the left. In the first calculation, the first non-zero digit is 5, so we keep it as well as the digit to its right, which is 2. Therefore, the rounded answer is -5.5.
In the second calculation, the first non-zero digit is 6, so we keep it as well as the digit to its right, which is 3. Therefore, the rounded answer is 6.3*10^13.
