10^{n}-1=1001
Swap sides so that all variable terms are on the left hand side.
10^{n}=1002
Add 1 to both sides of the equation.
\log(10^{n})=\log(1002)
Take the logarithm of both sides of the equation.
n\log(10)=\log(1002)
The logarithm of a number raised to a power is the power times the logarithm of the number.
