1 answer

The number of library visits before examination day is 2×10^3 and the number of library visits in an average week is 5×10^2.

To find how many times higher the number of visits before examination day is compared to the visits in an average week, we can divide the number of visits before examination day by the number of visits in an average week.

So, the calculation would be (2×10^3)/(5×10^2) = 2×10^3/5×10^2 = (2/5)×(10^3/10^2) = 0.4×10^(3-2) = 0.4×10^1 = 0.4×10 = 4.

Therefore, the number of library visits before examination day is 4 times higher than the number of library visits in an average week.
