To convert the number \( 7.3 \times 10^{-8} \) into decimal notation, you need to move the decimal point 8 places to the left since it is a negative exponent.

Starting with 7.3:

  • Move the decimal point 1 place to the left to get 0.73.
  • Move it another 1 place to get 0.073.
  • Move it another 1 place to get 0.0073.
  • Move it another 1 place to get 0.00073.
  • Move it another 1 place to get 0.000073.
  • Move it another 1 place to get 0.0000073.
  • Move it another 1 place to get 0.00000073.
  • Move it another 1 place to get 0.000000073.

So the answer is:
