The radius of the earth's orbit is 150,000,000,000 meters. What is this number in scientific notation? A 1.5x10^-11 B 1.5x10^11 C 15x10^10 D 150x10^9
[The last time I looked, the Earth's orbit was ~ elliptical, so it has a semimajor & semiminor axis...]
B, C, and D are all correct. Is scientific notation supposed to be normalized, making B the only correct answer
Yes, that's the way it's usually taught in school. --Dan
