72000000\times 10^{n}=7200000000000000
Use the rules of exponents and logarithms to solve the equation.
10^{n}=100000000
Divide both sides by 72000000.
\log(10^{n})=\log(100000000)
Take the logarithm of both sides of the equation.
n\log(10)=\log(100000000)
The logarithm of a number raised to a power is the power times the logarithm of the number.
