2. Write 58100 in standard form.

A. 5,81 × 104 B. 0,581 × 105 C. 5,81 × 10-4

B. 0,581 × 105

To write 58100 in standard form, we need to determine the appropriate power of 10.

In this case, we can see that 58100 is larger than 10, but smaller than 100.

Therefore, we can write 58100 as 5.81 × 10^4.

Hence, the answer is A. 5.81 × 10^4.
