Answer please the question is in the picture ​

Answer 1

Answer:

The two marked in the image.

Step-by-step explanation:

In scientific notation you will want only the most significant non-zero digit before the comma.

The first underlined number has two digits before it, the correct representation should be $1.25\times10^4$

The second underlined number has a 0 leading digit, while the most significant non-zero digit is a 4. The correct represantation should be $4.5\times 10^2$

An extra case could be made for the second number of the list, since it has no decimal part, but the way I read it means "the instrument used to measure the data has 0 decimal places accuracy"
