The correct answer to this question is A. 9.4 x , 9.25 x , 2.5 x , 7 x
Explanation:
These numbers are written in scientific notation. In this system, the exponent shows the number of spaces the period has been moved to make the number shorter. Additionally, a positive exponent shows the number has a certain number of digits to the right, while a negative exponent shows the number has digits to the left. In this way, the numbers presented can be converted as:
9.4 x = 0.000000094 (Exponent indicates eight spaces to the left)
9.25 x = 0.00000925 (Exponent indicates six spaces to the left)
2.5 x = 2500 (Exponent indicates three spaces to the right)
7 x = 7000 (Exponent indicates three spaces to the right)
