Answer: 2.25x
![10^{-17}](https://tex.z-dn.net/?f=%2010%5E%7B-17%7D%20)
Scientific notation is used in science because the number can be vary from so much that using decimal is making it hard. The number expressed in
![10^{x}](https://tex.z-dn.net/?f=%2010%5E%7Bx%7D%20)
form. Both number in the question is already in scientific notation. Then to multiply the number and keep it at scienfitic notation the calculation should be:
2.5 x
![10^{-8}](https://tex.z-dn.net/?f=%2010%5E%7B-8%7D%20)
x 9 x
![10^{-10}](https://tex.z-dn.net/?f=%2010%5E%7B-10%7D%20)
= 22.5 x
![10^{-18}](https://tex.z-dn.net/?f=%2010%5E%7B-18%7D%20)
= 2.25x
