Answer 2

D. 0.0000000654

Explanation:

The exponent determines which way the decimal moves. If the exponent is positive the decimal moves to the right, and negative means it moves to the left.

Since the exponent, in this case, is -8, the decimal moves 8 places to the left.

6.539058 E -8 --> 0.00000006539058

This can be rounded up to 0.0000000654
