What is the solution to the problem expressed to the correct number of significant figures?

[tex]$2.13 + 1 = ?$[/tex]

A. 3
B. 3.0
C. 3.1
D. 3.13


Sagot :

Let's solve the problem step-by-step and ensure the final answer is expressed with the correct number of significant figures:

1. Initial Addition:
- First, we add the numbers: [tex]\(2.13 + 1 = 3.13\)[/tex].

2. Determining Significant Figures:
- The number of significant figures in a result should follow the least number of significant figures among the input numbers.
- Here, [tex]\(2.13\)[/tex] contains three significant figures, and [tex]\(1\)[/tex] contains one significant figure.

3. Applying Significant Figures Rule:
- Since [tex]\(1\)[/tex] has only one significant figure, the result should be rounded to one significant figure.

4. Rounding the Result:
- The number [tex]\(3.13\)[/tex] rounded to one significant figure is [tex]\(3\)[/tex].

Thus, the correct answer, expressed to the correct number of significant figures, is [tex]\(\boxed{3}\)[/tex].
