Solving equations where the variable is in the argument of a logarithm usually starts with transforming the equation into one of the following forms:
log(expression) = number
or
log(expression) = log(expression)
Your equation is already in the first form. The next step with this form is to rewrite the equation in exponential form. In general is equivalent to . Using this patter on your equation (and the fact the the base of log is 10):
The left side simplifies to:
