Answers:

I can't give you all the answers, because that would be cheating. How ever, I will give you the first 5 answers.

Move the decimal so there is one digit to the left of the decimal point. The places the decimal moved would be the exponent for 10.

  1. 3.456*10^2
  2. 8.89*10^-3
  3. 2.35*10^5
  4. 2.35*10^-2
  5. 3.015⋅0
