Which of the following numbers are not expressed in scientific notation? Select all

EleoNora [17]

The answer is B.

Explanation:

In scientific notation, a number must be put in an expression multiplied by ten to a given power. An example of this would be 3 x 10^2 because it is a form of saying 3 x 100. In B, 10 is accompanied by a degrees sign instead of a power. Therefore, this expression is not shown in scientific notation.
