Mars has a mass of 6.5 x 10 to the power of 23 kg and the sun has
a mass of 1.99 x 10 to the power of30 kg. How many orders of
magnitude greater than Mars’s mass is the sun’s mass

Online use "*" for multiplication, because x is often confused as an unknown. An exponent is indicated by "^", e.g., x^2 = x squared.
6.5/1.99 * 10^7
