No, do you want me to guide you through it or do you want to try one more time?

\[\large (2.5 \times 9)(10^{-8} \times 10^{-9})\] However, remember that the bases (in scientific notation) needs to be between 1 and 10.

explain
calculusxy
  • calculusxy
Your product is really 22.5 (which is not between 1 and 10) so you need to move the decimal place to the left to make it 2.25 (which is between 1 and 10).
calculusxy
  • calculusxy
When you do that, you need to do an extra step

wow confusing

When you multiply 2.5 and 9, you get 22.5, which is not in scientific notation, so you must change it back
calculusxy
  • calculusxy
\[\huge 2.25 \times 10^1 \times 10^{-18}\]
narissa
  • narissa
so a
calculusxy
  • calculusxy
\[\huge 10^1 \] is needed because you moved the decimal one place to the left. Now the reverse can be applied to when you need to move the decimal place to the left. \[\huge 10^{-1}\]

No, it will still be negative
calculusxy
  • calculusxy
Not really what is \[\large 1 + {-18} \]
calculusxy
  • calculusxy
That will be your exponent, while 2.25 is your base.
