Question

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

34.5 x 107
A:5.02 x 103
B:2 x 10°
C:0.4 x 101
D:7.29 X 10-3

Answer 1

The answer is B.

Step-by-step 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.
