Final answer:
To round 2382 to 2 significant figures, we keep the first two digits and change the rest to zeros, resulting in 2400, since the third digit was greater than 5.
Step-by-step explanation:
To round the number 2382 to 2 significant figures, we follow the rules of significant digits.
The first two digits, '23', are the significant figures we want to keep.
To determine whether to round up or down, we look at the third digit which is '8'.
Since '8' is greater than 5, we round up the second significant digit '3' by one, resulting in '24'.
The remaining digits become zeros.
Therefore, 2382 rounded to 2 significant figures is 2400.
