Primarily because we count in tens and the SI system is based on powers of ten.
It is: 7.0*10-9 when in scientific notation
10 is the base in this case.
It is not. "Scientific notation" uses a base of 10. The correct notation would be 1.251 x 10^8
Shift a decimal place to the right, so the exponent for base 10 is -1. Then, the term in scientific notation is: 3.456789 x 10-1
Shift a decimal place to the left, so the exponent for base 10 is 1. Hence, the term in scientific notation is: 4.5668 x 10

1645.6 in scientific notation is 1.6456 x 10³. Move 3 decimal places to the left, so the exponent for base 10 is 3.
Move 3 decimal places for 1652.0 and the exponent for base 10 is 3. Therefore, the term in scientific notation is 1.652 x 10³.
Scientific notation is used when numbers are very large or very small as for example 1,000,000,000,000 is 1.0*10^12 in scientific notation
It is: 2.7*10^0 in scientific notation
Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1
It is: 1.315*10^10 in scientific notation
It is: 4.871*10^10 in scientific notation
