How do you express 480 in exponential notation only using one significant figure?

We need to first move the decimal two (2) places to the left:
480 = 4.80 x 102
The 2 in 102 comes from how many places we moved the decimal. It's positive because the number it represents is larger (480 > 4.8)
With one significant figure, we need to round to the nearest whole number:
5 x 102
The answer is 5 x 102

How do you write 7 billion in scientific notation?
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
