To raise a term with an exponent to another exponent, retain the base and multiply the exponents:

A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.

A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.

To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 200 meters to kilometers, divide the distance by 1000 to get 0.2km then add the remaining distances:

total distance = swim + bike + run
total distance = 0.2km + 40.7km + 13.3km
total distance = 54.2km

Jennifer scored 76% on the test meaning she earned 76% of the possible points on the test. There were 200 possible points on the test so she earned 200 x 0.76 = 152 points. Each question is worth 4 points so she got \( \frac{152}{4} \) = 38 questions right.
