Explain how this is an exponential function:
x: 1 ** 2 ** 3 ** 4
y: 5 ** 25 ** 125 ** 625
Multiplying by 5 each time; 5 is base being raised to a power

Astronomers measure large distances in light-years. One light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles. Suppose a star is 4.2 × 102 light-years from Earth. Approximate that in miles, in scientific notation.
