Understand rational exponents and simplify expressions with examples. Discover Kepler's third law and calculate orbital periods with given functions. Find lengths of Venusian years and express in simplest form.
E N D
Kepler’s third law of orbital motion states that you can approximate the period P (in Earth years) it takes a planet to complete one orbit of the sun using the function , where d is the distance (in astronomical units, AU) from the planet to the sun. Find the approximate length (in Earth years) of a Venusian year if Venus is 0.72 AU from the sun.
