To find out how many times higher the number of library visits before the examination day is compared to the number of visits in an average week, we can divide the visits before the examination day by the visits in an average week.
(2 x 10^3) / (5 x 10^2)
Simplifying this expression, we get:
(2 x 1000) / (5 x 100)
2000 / 500
4
Therefore, the number of library visits before the examination day is 4 times higher compared to the visits in an average week.
(2 x 10^3) / (5 x 10^2)

To express $15,528.23 in the form of a×10n, we need to determine the value of a and n.
Given that the bank deposit amount is $15,528.23, we can rewrite it as 1.552823×10^4.
Therefore, a = 1.552823 and n = 4.
So, $15,528.23 can be expressed as 1.552823×10^4.
