Two weeks before an examination day, a librarian monitored the number of students who visited the library. Then they compared it with the number of visits made in an average week. Approximately 2×103
visits were reflected in their logbook during this two-week period, while only about 5×102
were reflected on an average week. How many times higher is the number of library visits before examination day compared to the library visits in an average week? Your answer should be a whole number.

To round 7,803,100 to the nearest place value, we look at the digit in the ten-thousands place, which is 3. Since 3 is less than 5, we round down. Therefore, the rounded value is 7,800,000.
Expressed in the form of a single digit times an integer power of 10, this number becomes 7.8 × 10⁶.

The number of visits before the examination day is approximately 2×10³, while the number of visits in an average week is about 5×10².
To find how many times higher the number of visits before the examination day is compared to the number of visits in an average week, divide the number of visits before the examination day by the number of visits in an average week:
(2×10³) / (5×10²)
Simplifying this expression, we can cancel out a factor of 10:
(2/5) × (10³/10²)
2/5 = 0.4, and 10³/10² = 10.
Therefore, the number of visits before the examination day is 0.4 times 10, which equals 4.
Thus, the number of library visits before the examination day is 4 times higher compared to the library visits in an average week.

To find the amount in the form of a×10ⁿ, we need to determine the values of a and n based on $15,528.23.
To do this, we can round $15,528.23 to the nearest place value, which is the nearest dollar. So the rounded amount is $15,528.
We can then express $15,528 in scientific notation form. Since $15,528 is greater than 10 but less than 100, the single digit a is 1 and the power of 10, n, is 4.
Therefore, $15,528.23 can be expressed as 1×10⁴.
