Answer:

#40,000,500#

Explanation:

  1. This is the reverse process of writing standard scientific notation;
  2. First, look at the exponent which is 7;
  3. Move the decimal point 7 times to the left bearing in mind that moving the decimal to the left means a negative exponent, and that would cancel out the exponent;
  4. Position your decimal and apply appropriate commas to identify its place value and readability;
  5. The standard notation is #40,000,500#.
