What number has 9 zeros at the end?
As you know, a billion is a 1 with nine zeros after it. We can write it as 1,000,000,000.
What is the number 1000000000000000000000?
One million has six zeros (1,000,000). Ten million has seven zeros (10,000,000). One hundred million has eight zeros (100,000,000). When you make the jump from one large number to the next designation (for instance, from one million to one billion), you'll add a group of three zeros.
What is 1 followed by 7 zeros?
1 billion has 1 followed by 9 zeros, that is, 1, 000, 000, 000 and it is represented as \(10^9 \) (ten to the ninth power).
