Answer:
7.07 x 10^-8
Explanation:
Count the amount of times that you can move the decimal point back until you have a number that is between 1-10. This one you would go back eight times. Then you take the number (7.07) and write 7.07 x 10^-8
the negative 8 is because you moved it back 8 times. If the number you were trying to put in scientific notation were 707000000, then your answer would be 7.07 x 10^8
it would be positive because you moved it forward.
hope this helps!!!
