Answer:
A: 3.4 x 10^7
Step-by-step explanation:
To write an answer in scientific notation you need to move the zero so that there is one number in front of it. Then you multiply that number by how many zeroes it would be to get the number back to its original form.
In this case we are moving the zero 7 digits to the left to make the number 3.4. And since the number was originally bigger it would be times a positive ten to the power of seven, so your answer would be A: 3.4 times 10 to the power of 7.
