Interpretation:
How to express the number 0.000123 in scientific notation has to be selected from the given options.
Concept Introduction:
In scientific work, large and very small numbers occurs frequently. But it is been observed that, to record these vast numbers or very small numbers is difficult because, the numbers may get missed while recording them. It is time consuming and the possibilities of error occurrence are also high. Hence to overcome these demerits, a method called scientific notation is used. In this method the numbers are expressed in form of “
