  2. 7.1 nth Roots and Rational ExponentsNotes C Example 5:Evaluating a Model with nth Roots The total mass M (in kilograms) of the magnetic sail is, in theory, given by the formula below where m is the mass (in kilograms) of the magnetic sail, f is the drag force (in newtons) of the spacecraft and d is the distance (in astronomical units) to the sun. Find the total mass of a spacecraft that can be sent to Mars using m = 5000kg, f = 4.52 N and d = 1.52 AU. M = 0.015m2 fd 4/3

  3. Example 6:Solving an Equation Using an nth Root The Olympias is a reconstruction of a trieme, a type of Greek galley ship used over 2000 years ago. The power P (in kilowatts) needed to propel the Olympias at a desired speed s (in knots) can be modeled by this equation: P = 0.0289s3. A volunteer crew was able to generate a maximum power of about 10.5 kilowatts. What is their greatest speed?

  7. Example 2:Using Properties of Radicals

  8. For a radical to be in simplest form, you must not only apply the properties of radicals, but also remove any perfect nth powers. Example 3:Writing Radicals in Simplest Form
