To compare \( 8.9 \times 10^5 \) and \( 3.9 \times 10^8 \), we can express both numbers in standard form.

1. \( 8.9 \times 10^5 = 890000 \)
2. \( 3.9 \times 10^8 = 390000000 \)

Now, we can see that:

- \( 890000 \) (which is \( 8.9 \times 10^5 \)) is much smaller than \( 390000000 \) (which is \( 3.9 \times 10^8 \)).

Thus, \( 8.9 \times 10^5 \) is smaller than \( 3.9 \times 10^8 \).

So the answer is:

**8.9×10^5**.
