10 to the power of 3 is 1,000, so the logarithm is 3.

How this was calculated
ln(1,000) ÷ ln(10) = 6.907755 ÷ 2.302585 = 3
Check: 10³ = 1,000

The logarithm answers the question: to what power must the base be raised to get x? Any base can be reduced to the natural logarithm ln using the change-of-base formula.
