Explanation:
The exponent of a factor inside a logarithm can be expanded to the front of the expression using the third law of logarithms. The third law of logarithms states that the logarithm of a power of
is equal to the exponent of that power times the logarithm of

Now let's implement this with the values we know.
![x*log(10)=3](https://img.qammunity.org/2020/formulas/mathematics/middle-school/jk7azqrr909xrg1jkeh3w974p305qz6ikq.png)
The logarithm base 10 of 10 is 1.
