How Do You Convert From Scientific Notation to Decimal Notation?

Convert '3.25 x 109' and '4 x 10-7' to decimal notation

Summary

  1. '3.25 x 109' and '4 x 10-7' are in scientific notation
  2. If the exponent is positive, move the decimal to the right
  3. Write zeros in all the empty spaces created by moving the decimal
  4. Rewriting the answer helps it look better
  5. If the exponent is negative, move the decimal to the left

Notes

    1. We want to look at the exponents for the number of places and the direction in which to move the decimal
