Answer:
2.1 * 10^7

Explanation: To find things in scientific notation you basically just move the decimal point so that the number is in the one's place. The exponent is the number of times you moved the decimal place. Ex. 0.000003467 would be 3.467 * 10^-6 because you moved the decimal point six times to the right.
