(a)
Interpretation:
The number
Concept introduction:
The scientific notation is the standard method of representation of a long or tedious measurement. The number is expressed as number times ten raised to some power.
For instance, mass of a proton is conveniently expressed as
While a number is written in scientific notations it is scaled down to some digit between 1 to10 ten and the places that previously contain zeroes are changed to ten raised to some power.
