Which of the following can be an example of scientific notation?

Scientific notation is a way to express very large or very small numbers in a compact form, typically written as a product of a number between 1 and 10 and a power of ten. In scientific notation, the first part (the coefficient) must be a number greater than or equal to 1 and less than 10, and the second part is denoted as 10 raised to an integer exponent.

The expression 6.02 x 10^23 is a clear example of scientific notation because it follows the specific structure: the coefficient 6.02 is between 1 and 10, and it is multiplied by 10 raised to the power of 23, which indicates that this number is quite large. This format allows for easier reading and comprehension, especially in fields like science and engineering where extremely large or small figures are common.

In contrast, numbers like 100, 0.001, and 50% do not fit the requirements for scientific notation. The number 100 can be rewritten in scientific notation as 1.0 x 10^2, but it is not presented in the conventional scientific notation format. Similarly, 0.001 could be expressed as 1.0 x 10^-3, which
