100 billion in scientific notation is: 1.000000e+11
It is: 7.5*10^9 = 7.5 billion in scientific notation
6.32 billion in scientific notation is: 6.32 x 109
The question is: How can you write 319 billion in scientific notation? The easiest way for me to explain Scientific Notation is the form of writing a very large or a very small number, by using minimal numbers. For example; 319 billion is written 319,000,000,000. The first thing we do is arrange the number with the decimal point being behind the very first number. REMEMBER, the decimal point will ALWAYS be behind the first number. So we start off by writing 3.19. We then multiply this times 10 to a certain power to get billions. So therefore, in 319 billion, how many spaces do we have after the decimal if we put the decimal behind the number 3? For example, if I just wrote 3.19000000000. Because I put the decimal behind the first number, I now have 11 places after the decimal. Therefore, to write Scientific Notation, you would take the numbers 3.19 and multiply times 10 to the 11th power. That's because there are 11 spaces after the decimal. So to write it in its smallest form, you would put 3.19 x 10^11.
In Scientific Notation, 319,000,000 is 3.19 x 10^8.
319 000 000 = 3.19 * 108
