7 x 109
7 billion in Scientific Notation = 7 x 109To express a number in scientific notation, you first need to divide it by a power of 10 such that the greatest significant figure is in the units place. In this case, that can be done by dividing 7 billion by 1 billion to give 7. Next, the power of ten that was used should be placed alongside as a multiplication. We used 1 billion, which is the 9th power of 10. Thus, 7 billion in scientific notation is 7x109
Something that is a billion starts with base 109. Therefore, the term in scientific notation is 7.0 x109
"Billion" usually has the meaning "thousand million". So 7 billion = 7 x 109.Traditional UK usage has billion meaning "million million". This in exponential form (scientific notation) is 7 x 1012.
6,100,000,000
The scientific notation of 31 million is 3.1 x 10^7. Thirty-one million has 8 decimal digits.
There's nothing to change here. There is no advantage or reason to write 7.060 in scientific notation. Technically, however, it could be written as 7.060 × 100, but this is not normally done.
It is 1.54*10^4 in scientific notation
1.67x10^-6
42.4 billion * 57 million = 2.4168*10^18.

It is: 8.205*10^2 in scientific notation
The Earth is estimated to be around 4.5 billion years old, not 7 billion years. This age is based on scientific evidence such as radiometric dating of rocks and meteorites.
