The number given is very large, and scientific notation is a way of expressing large and small numbers in a more compact form. To write this number in scientific notation, we need to move the decimal point to the left until there is only 1 digit before the decimal point. This means we need to move the decimal point 21 places to the left, so the answer is 3.06 x 10^21. Choice B is the only option that matches this answer.
