D. 23,000 + (4.5 x 103)

Answer 1

Answer:

Option C- 23,000+(4.5+103) is correct

Step-by-step explanation:

In calculator, numbers in scientific notation must be entered in 'e' notation.

For example, $\[1.234\text{ }\times \text{ }{{10}^{40}}\]$ is entered as $\[1.234E40\]$

Thus, expression  $\[23,000+\text{ }4.5E3\]$ can be written as $\[23,000+\text{ }4.5\times {{10}^{3}}\text{ }\]$.

Therefore, option C is correct.
