What is the number seven hundred thirty-one million, nine hundred thirty-four thousand, thirty written in standard form

For this, we take three number digits in the question. So on the far left would be "731" and then a comma. And that brings us to "731,". Next we take 3 more number digits. So we take "731," we put "934" after it. Which comes to "731,934,". Then after all of that we put "030" after "731,934,". Which is now "731,934,030".
