To find the product of 300,000,000 multiplied by 900,000,000, you can follow these steps:

1. Multiply the values after removing the commas: 300,000,000 x 900,000,000
This calculation simplifies to 300 x 900 = 270,000.

2. Count the number of zeros in the original numbers.
Since there are eight zeros in 300,000,000 and nine zeros in 900,000,000, add the number of zeros together: 8 + 9 = 17.
